Paola Telfer, the founder of Sens.ai, and Dr. Drew Pierson, a board certified neurotherapist with 20 years in neurofeedback, say lasting brain change comes from teaching the brain its own states. Their headset reads your brainwaves, rewards the patterns you want and tunes its light to your own frequency.

Highlights

  • Brainwave ocean: Telfer compares brainwaves to the ocean: all five bands run at the same time, and one simply becomes dominant depending on what you are doing. [07:05]
  • Seven digit memory: Pierson links the seven digits of a phone number to theta, which runs at about 7 cycles per second, while gamma binds those digits into memory. [10:21]
  • Zero effect at 10 Hz: In four years of prototype testing, a generic 10 Hz light pulse did nothing for some people until the team read their own frequency and stimulated there. [39:37]
  • Binaural beats: Pierson says binaural beats measured only about 20 or 30% effective in their testing, partly because so many people have auditory processing issues. [43:56]
  • Millisecond precision: The built-in assessment times your brain responses to 1 millisecond, tracking accuracy, reaction time and how fast you notice and adapt to an error. [49:51]

Why Home Neurofeedback Matters

Neurofeedback used to mean a clinic, a brain map and a five figure bill for a single intensive week. Pierson spent decades in those clinics working with fighter pilots, Navy SEALs and pro baseball players, and Telfer built Sens.ai to bring that training into a headset you can use at home.

The bigger idea is a flexible brain. You do not want to live in beta any more than you want to live in delta, and training lets you shift into the state a task needs, then keep that skill once the headset comes off.

How Does Neurofeedback Train the Brain?

Neurofeedback reads your brainwaves through EEG and turns them into sound and visuals. When your brain produces the pattern you are training, the cue gets more pleasant, and that reward is what teaches it. Pierson calls this operant conditioning, the same principle Pavlov used.

Because the feedback works faster than analytical thought, the most common question, what should I think about, has a strange answer: nothing. Sens.ai ties instruments to bands, a high flute for gamma, a trombone for alpha and a deep bass for theta. You simply lean toward the sound you like, and the brain follows.

The goal is independence. Pierson does not want anyone wearing a headset all day, and Telfer designed the system to teach new mental habits without building a dependency, much like an accelerated and measured form of meditation.

What to do: During a session, stop trying to think your way into a state. Relax, listen for the instrument the program rewards and let the volume guide you.

It’s actually feeling into the feedback, into the sounds, and the visuals.

Why Does Personalized Light Stimulation Matter?

The headset carries seven LEDs at 810 nm on its flex cap. Telfer groups its functions as boost, train and assess, and boost is the light session. Because the same cap carries electrodes, it can see where your alpha actually sits on a given day, say 9.5 Hz one day and 10.5 Hz the next.

It then stimulates at that resonance or nudges it slightly higher. That design came out of prototype testing, where a fixed 10 Hz pulse failed some users. Pierson adds that light gives neurons energy, raising ATP through cytochrome c oxidase in the mitochondria, and increases blood flow and oxygen to the brain.

Telfer does not approve of multitasking during a boost, but she knows people do it. If you must, Pierson suggests reading a physical book, and both say the guided meditations paired with each boost do much of the work.

What to do: Pair each light boost with its guided meditation, and if you want to do something else at the same time, make it a paper book rather than email.

not just stim 10 hertz blindly for everybody.

How Should You Start a Brain Training Routine?

Sens.ai is gamified, and missions unlock in order. After the assessment, you get missions for sleep, brain fog, attention or stress, and the early work centers on alpha, beta and SMR to build resilience. Telfer says you cannot cherry pick your way to the advanced states.

Later layers mix frequencies and add synchrony, getting the brainwaves to play like instruments in one symphony. Pierson asks beginners to train somewhere quiet first and bring in distractions only once they can hold a state. Nick found calm training frustrating for about 10 sessions despite a decade of meditation, while focus clicked on the first try.

Outside the headset, Pierson puts sleep first and calls it nonnegotiable. Sun, minerals and micronutrients come next, and nootropics such as piracetam, omega-3s, lion’s mane and creatine are the final layer.

What to do: Follow the recommended missions in order, train in a quiet room and fix your sleep before you add any nootropics.

Until you’ve done the focus training, it’s gonna be very difficult to meditate.

Checklist: Getting Started With Home Brain Training

Use these steps in your first weeks with a neurofeedback headset.

  1. Wet the electrodes: add a couple of drops of water and fit the headset snugly before you start.
  2. Take the assessment first: let it set your baseline and recommend a mission.
  3. Open with your breath: use the heart sensor session to settle in before the brain work.
  4. Sit still and stay quiet: skip gum and jaw clenching, since the system pauses rather than train on noise.
  5. Review your progress: compare assessment scores over weeks instead of judging one session.

Key Terms Quick Reference

  • [26:32] Biofeedback: Biofeedback means biological feedback: a device detects a signal from your body, such as an EEG wave, and plays it back to you as a cue you can learn from.
  • [27:35] Operant conditioning: Operant conditioning is learning through reward, where the brain repeats the activity pattern that earns a pleasant cue and drops the one that does not.
  • [32:49] Heart coherence: Heart coherence is a paced breathing state that balances the sympathetic and parasympathetic nervous system and brings the heart and brain into harmony.
  • [38:00] Transcranial photobiomodulation: Transcranial photobiomodulation is light sent through the skull to the brain, which Sens.ai delivers at 810 nm and pulses from 1 to 1024 Hz.
  • [46:58] Event related potentials: Event related potentials, or ERPs, are the standard lab method for measuring how quickly the brain processes a task or stimulus.
  • [01:17:08] Rich club network: Rich club network is the term Pierson uses for 12 major brain networks that combine, led by the default mode, salience and executive networks.

Frequently Asked Questions

What does each brainwave band do?

Pierson says beta handles focus and problem solving and drains you over time, while alpha is regenerative. Theta taps the subconscious and releases stress. Delta drives hormones and the brain’s waste clearance during deep sleep.

Do you need a clinical brain map before using Sens.ai?

No. A brain map compares you to a database and is mostly used to find pathology. Sens.ai baselines you across several sessions at home, so it can tell whether you are having a good day and adjust how hard it pushes.

Will you depend on the headset to reach these states?

No. Pierson says the point is to switch on a state when you want it, without the headset. Telfer built the system to teach mental habits rather than create a dependency.

Is there a low cost alternative to a neurofeedback headset?

Telfer points to breathwork, especially heart coherence. She says a simple, inexpensive device from HeartMath can do a lot for your brain and nervous system on its own.

Nick Urban [00:00:05]:
What if you could upgrade your intelligence? And not just your IQ, but all the different forms of intelligence?

I’m talking thinking faster, making better decisions, mastering your ability to self regulate emotionally, improving verbal fluency, shooting your motivation through the roof and keeping it there, sharpening your focus and concentration, and even elevating your confidence?

Not only that, but doing it the natural route using a technology that even once you stop using it, the benefits stick around for quite a while? Now that might sound far fetched, But there is a system that I’m quite excited about that I’ve been using for about 90 sessions now, and that is called Sens.ai. It’s the world’s 1st 5 in 1 brain training system.

Each of your sessions is personalized based on your body’s biofeedback signals, And the session is actually adapted and tweaked and improved in real time. This futuristic technology was just released to the general public. I preordered in the middle of 2022, and it’s finally here.

So I brought on the team to the podcast to share what they’ve built and how it can transform your mind. Our 2 guests on today’s show are Dr. Drew Pierson and Paola Telfer. Dr. Drew Pierson is a doctor of both Western and Eastern medicine and a board certified Neurotherapist with 20 years of neurofeedback experience.

He’s a decorated submarine veteran that served 6 years in the US Navy, the former head of neuroscience at 40 Years of Zen, where he guided elite executives, enlightened minds, and athletes to peak performance. Paola, on the other hand, is a tech entrepreneur with a passion to develop technology that improves lives.

She discovered brain training’s transformative impact on her own life and made it her mission to share this widely with everyone. From there, she founded Sens.ai, and the rest is history.

Nick Urban [00:02:25]:
If you wanna check out the things we discuss in today’s episode, the show notes with all the links and resources will be available. You can also check out my YouTube review of Sens.ai showing you the practicals of how it works, what my session looks like, and everything you need to know, or the written article that I did to accompany that. Alright.

Without further ado, Team Sens.ai. Paola and Dr. Drew, welcome to the show.

Paola Telfer [00:03:21]:
Hi, Nick. Thanks for having us.

Dr. Drew Pierson [00:03:24]:
Yeah. Thanks for having us.

Nick Urban [00:03:25]:
It’s great to have you guys here. Let’s begin today with a couple of both of your nonnegotiables you’ve done for your health, your performance, and your bioharmony.

Paola Telfer [00:03:38]:
I always start my day before checking my phone. I always do something for my brain. In the morning, you’re kinda still in this dreamy state, and it’s a really nice time for meditative type practices.

So I did heart rate variability training, very heart centered with a gratitude meditation, transcranial photobiomodulation that was like a nice alpha tweak, tuning up my peak alpha frequency, and then followed by some neurofeedback that was a mix of alpha, gamma, and again tuning up that peak alpha frequency.

So that’s what I did this morning, all within about a 45 minute total, before I looked at my phone.

Nick Urban [00:04:32]:
And for anyone listening in who does not understand any of those words, we will clearly define what each of those mean and why you’d wanna go about those. Dr. Drew?

Dr. Drew Pierson [00:04:43]:
So sleep is nonnegotiable for me. It’s so important to set up your sleep environment and have good sleep hygiene and have a good night of sleep before you start anything the next day. What I did today, I came in and used what I call another acronym here.

CVAC is a cyclic variable altitude pod, basically, and I combine that with the good old Sens.ai and able to train inside something like that and do HRV, photobiomodulation. And I’ll either do 1 of 2 programs typically in there. 1 is focus. It prepares me for the day cognitively focus wise. And the other 1 is Deep Calm, which is a deep relaxation one that we use.

That’s like caramel. It’s just so sweet.

Nick Urban [00:05:44]:
Yeah. And why inside the CVAC machine?

Dr. Drew Pierson [00:05:47]:
I think for stacking and time wise because if I’m using that, you know, 30 minutes, then I have to go and do neurofeedback for 30 minutes. And in the CVAC, it’s increasing vascularity and brain blood flow and better oxygenation of the system. So if we combine those, I think I’m getting a better response cognitively from that.

Nick Urban [00:06:10]:
So, basically, you’re amplifying the effects of your training?

Dr. Drew Pierson [00:06:13]:
Yes. And I always do my herbs in the morning, so all the Chinese herbs and acetylcholine and essential fatty acids, piracetam, is typically what I’ll take in combination.

Nick Urban [00:06:30]:
I didn’t tell either of you guys this, but I also did some training this morning. I did some heart coherence, which is like HRV biofeedback. And then after that, I did a focus session. We will get into what all of that means in a few minutes, but can you guys first break down what are brainwaves?

Paola Telfer [00:07:05]:
I’ll start with a layman’s approach and then Dr. Drew can go deep if we want to. So I like to use the ocean analogy when we think about brainwaves. The brain has an electrical nature and, like you’re alluding to with the neurochemicals, a chemical nature.

But if we look at neurons firing, they are creating electrical activity in the brain that we can measure. We can measure it at the scalp. So that’s really what we’re doing with neurotech devices and when you hear the term EEG, we’re measuring that electrical neural activity. And so the brainwaves, there’s 5 frequency bands that are defined.

They’re that oscillation that’s happening and has been broken down in spectrum. And they’re all happening at the same time, which is something important to note. We’re not exclusively ever like an alpha. Alpha just becomes more dominant. It becomes more powerful.

Paola Telfer [00:08:00]:
So what we’re doing is right now, let’s say, we’re mostly in a beta dominant state where our attention is directed outward. We’re perceiving our environment with our senses. And when we go to sleep at night, we’re at the bottom of the ocean, which is more delta.

And then in between, there’s all these subtle states that are really powerful and very beautiful that we tend to not be able to tap into with lucidity. So if you’ve ever tried meditation and you sit down for a minute and then you fall asleep, that’s us going straight from beta to delta just because we haven’t developed that skill set of navigating the ocean in between.

From the top to bottom, beta, the next level would be more alpha. And that’s more this relaxed, spa-like brainwave, which is actually still very embodied. And then a little bit deeper, now we’re going into theta. Theta is like more float tank, deeper meditative states, and then we go into delta.

Paola Telfer [00:09:34]:
So the one that’s missing, the 5th one, is gamma. Gamma is this enigmatic brainwave state that’s been detected in people who have meditated for many years. They’ve done studies on monks and seen very high gamma amplitude and high gamma synchrony. Gamma is actually the fastest of all the brainwaves, higher than beta, but we think of it as being deepest.

It’s actually a bit of a juxtaposition. It’s the deepest in the ocean, but it’s like you’ve got sunlight in there. So there’s a lot of lucidity and awareness with it. That gamma state is very, very creative.

Dr. Drew Pierson [00:10:21]:
The only thing I’d probably add, gamma is, as far as I’m concerned, consciousness. It brings about consciousness. If you see a red ball and it’s bouncing, and you have to correlate that with the color red, and it’s a ball, gamma really binds that together. Also gives us a memory function. One of the things we do in a telephone is 7 digits.

That nests in what we call theta. Theta is about 7 cycles per second. But gamma elicits this fact that we can actually memorize things in those 7 digits. That’s why inherently we tend to have a 7 number gap or limit for memorization. Gamma is one of those eureka frequencies, and it really binds together the memory from the hippocampus.

Nick Urban [00:11:38]:
So the way I’ve thought about it, I generally thought that the faster the frequency, the less restorative. For example, if you go down into delta when you’re sleeping, that’s what allows a lot of the different biochemical processes to occur, and so the body can repair and regenerate.

And maybe with the exception of gamma, as you go higher, faster frequency, that’s less restorative and can be depleting of the brain’s resources, such as when you’re in a beta dominant state indefinitely?

Dr. Drew Pierson [00:12:11]:
Typically, yeah, beta will, if you’re doing focus and concentration and analytical thought and problem solving, all the things that go along with beta, that can be draining over time. Alpha is much more regenerative, and that’s why meditation actually brings about that regenerative nature.

Theta taps much more into the subconscious, and it’s in that dreamlike state. It releases a lot of stress in that lower frequency, and that can be very regenerative. Delta is a pure physiologic aspect that really taps into hormones and cycles, what we call GLIMP or brain lymph.

Pumping the brain of getting out the stuff that we need to get out and bringing in new nutrients and blood flow and oxygen.

Paola Telfer [00:13:14]:
Nick, I think it’s a good point that you’re bringing up because when we approach this in Sens.ai, it was really about creating a flexible and balanced brain. You don’t want to always be in beta any more than you always wanna be in delta. So we’re trying to help people who are maybe more analytically centered to be more heart centered, and vice versa.

So people can be more active in the world the way they want to be depending on the task at hand.

Nick Urban [00:13:45]:
Yeah. I was about to ask why you guys went about this entire mission in bringing this product to life? What is the benefit of getting more granularity in your ability to access different brain states?

Paola Telfer [00:13:58]:
For sure. I can start with how I came across neurotechnology. When I first met Drew, many years ago, it was when he was working on my brain. And that was because I’d had a motor vehicle accident. And so I was in a healing journey. But in that process, I discovered that it actually improved my meditation practices.

I was actually able to more consistently, more precisely, target different meditation styles. And it also really helped me in my cognitive performance. I was running another startup at the time. And so I realized that depending on the type of brain training, you could actually be learning to shift gears and it could help different aspects of your life.

And that’s when my eureka moment was about everybody needs this. So it was about how do we make this smaller, less expensive, and efficacious at scale.

Nick Urban [00:15:32]:
What is it that you can get out of brain training? Like, say I go in, and I have these specific goals regarding performance, or I suffered a TBI, say, from playing rugby or American football. What are the different things that it can do?

Dr. Drew Pierson [00:15:51]:
That’s a very broad thing. We could take you to the peaks of these type states. The happiness of gamma, the insights that come along with it, we can help you focus better in certain frequencies with the beta frequencies. You can help the attention centers in the brain really bring themselves together to focus.

Alpha is much more of a meditation state, but it’s also necessary for any peak performance. If your alpha isn’t bursting right before you throw that rugby ball or throw a baseball or even while you’re driving, you’re gonna fail typically because the alpha is not there to really promote the smooth flow. Theta can be high or low depending.

And if that’s not regulated properly, you’re gonna either have attention issues or stress issues. And delta is so important for sleep, and if you’re not regulated in delta, you’re not gonna sleep well.

Paola Telfer [00:17:26]:
When we started looking at this because it is so broad, we looked at it like, well, the ultimate goal is really one of consciousness evolution. So how can we help people to move from more of the me centered, like self care, maybe evolve into a we sort of consciousness and into an all sort of consciousness.

But the first thing to do is to meet people where they are today. So even if I say I’m looking for peak performance, but I’m actually having pretty crappy sleep this week, I gotta deal with that first.

Paola Telfer [00:18:22]:
And so we actually start with what we call an assessment, so that people can focus on one thing at a time. The app is structured to be personalized and to be a journey that goes with you. We wanted something like a coach, like a brain coach, like having Drew on your shoulder whispering, hey, you should do a little beta today.

And so the concept of missions is if we were trying to help 1 person at a time with sleep, how was the quickest way for us to get them to better sleep? And so let’s get them to focus on these specific training programs between these weeks.

Nick Urban [00:19:54]:
That was one thing I noticed very quickly. At first, I was concerned that how am I gonna be able to choose between all these? But then once you actually start the mission, it guides you, and you don’t have to worry.

Paola Telfer [00:20:14]:
Absolutely. And some folks, since COVID, we’ve become so aware of brain fog and stress management issues. I think it’s important for us to acknowledge, even as peak performers, we have these sort of blocks. And there should be no shame in dealing with that. And you can deal with it privately. Sens.ai will guide you through that step by step.

Nick Urban [00:20:46]:
I think it’s pretty clear that there’s a foundational electromagnetic nature of the brain and of the body as first depicted by Robert Becker in his book, The Body Electric. But what about the chemistry side? Is there any interplay between working on the brain’s electromagnetic signature and frequency bands and then also the neurotransmitters or neurochemicals?

Dr. Drew Pierson [00:21:22]:
There is. Neurochemicals are very different from the neuroelectrical setup. The neurotransmitters are communication molecules, and they play a role in motivation or pleasure, mood regulation, attention, learning, and memory.

But what we find with neurofeedback and any form of photobiomodulation, it starts making these neurotransmitters more efficient, so you don’t need as much to get a lot further. They’re able to be in waiting rather than using them all and then be depleted. And it’s gonna bring down recovery times tremendously just because of that.

Nick Urban [00:22:46]:
Drew, Paola already described her background a little bit, but obviously, you’ve been involved in this for quite some time. Will you share a bit about your backstory?

Dr. Drew Pierson [00:22:55]:
I got into neurofeedback in the mid nineties and was able to train with some of the most incredible people that brought about neurofeedback into what we know it is today. Barry Sterman, Siegfried and Sue Othmer, Joel Lubar, Joe Kamiya, some of these greats that really set the stage for what I do right now.

I became addicted to how to change the brain without medication. I did pediatrics mainly for about 5 years before I went into more of a general practice, and then that evolved into a peak performance practice. Being in San Diego, I get to work with everything from fighter pilots to Navy SEALs to Major League Baseball.

It really brought about the aspect of what these peak brains and how they operate. How can we affect greater legions of leadership out there too.

Nick Urban [00:24:35]:
And one thing that came up when I was first researching this. I love the potential of neurofeedback and brain training. And there is research showing that it’s as great as you make it sound. At the same time, I was looking at how to actually do this.

And it seems like it was only available to the upper echelon of society because at a really high end clinic, a week of guided neurofeedback can be 5 figures. And for your average population, that’s just not accessible. And so when you have a system like Sens.ai, it’s taking that cost way down and allowing you to accrue the benefits every day.

Paola Telfer [00:25:36]:
Yes. For sure. I’ve done clinics like that, and then I was left with, the effects lasted for quite some time, but I wanted to take it to the next level at home. And with meditation alone and breath work alone, I was unable to do it. And I tried doing it with the devices available on the market. And then that’s where we thought, okay, there’s a gap here.

But to do it right, it’s gonna take us some time, and it did. It took us 5 years.

Nick Urban [00:26:15]:
So can you guys describe what is biofeedback? What is happening in the brain? How are you creating the cues to make this change?

Dr. Drew Pierson [00:26:32]:
All it means is we’re getting biological feedback. We’re detecting a wave, an EEG or electroencephalography. This electrical pulse coming out, we’re detecting it and providing feedback back to the system. Much like Pavlov did with the dogs.

When a person receives feedback during neurofeedback, it’s signaling the brain that that particular pattern of neuroactivity is good or desired. We’re giving them a reinforcement for that, and then we pull back the reinforcement when it doesn’t meet the criteria of what we’re looking for.

Paola Telfer [00:27:35]:
There’s neuroplasticity, that we’re aware. We can change our brains very much like we can change our bodies with training. And then there’s operant conditioning, and that’s what Dr. Drew is referring to. We’re reading the brainwaves when we’re doing neurofeedback training.

And when we’re doing the heart rate variability training, we’re reading the heart rate and converting that mathematically into heart rate variability. And so those biosignals, we change them into audio and visual cues. So you’re basically engaging with your biosignals in this audio visual experience. It’s much more accelerated learning.

Nick Urban [00:29:02]:
And this is because the brain doesn’t have any external facing sensors per se. So you’re putting an electrode and EEG on the brain, you’re reading the brainwaves.

When it dips out of what you’re training for, you get some kind of feedback or cue, and then the brain recognizes that and shifts its electrical activity towards what it thinks you’re looking for, and when it goes into the right band, then it gets a rewarding cue.

Paola Telfer [00:29:45]:
Yes. And what’s really interesting is that the feedback is faster than the speed of analytical thought. One of the most common questions people ask is, what should I be thinking about? And during neurofeedback, it’s like nothing. It’s counterintuitive, but it’s about not thinking about it.

It’s actually feeling into the feedback, into the sounds, and the visuals. In our system, we’ve associated certain instruments with certain wavelengths. We have a higher flute associated with gamma sounds, a trombone associated with alpha sounds, and a deeper bass associated with theta.

Paola Telfer [00:30:24]:
When you’re training, you just need to feel like I like the trombone. I wanna hear more trombones. And then the volume goes up higher. The trombones become more frequent. And as long as that’s pleasant for you, that will feel like a reward, and the brain will just follow. The brain will just know what to do.

Nick Urban [00:31:18]:
I like to think of this training as the mirror for your brain that you never had. So it can show areas in which you’re unable to otherwise, and by training those, all of a sudden that neural pathway becomes more active and the brain can access that even when you’re not using Sens.ai or any other system.

Dr. Drew Pierson [00:32:02]:
That’s the key for all of this. We don’t want a headset on all the time. We wanna be able to turn on these states of consciousness when we want rather than them controlling us.

Paola Telfer [00:32:49]:
We want the system to be teaching you how to do it without building a dependency. That’s why neurofeedback is the core, the beating heart of Sens.ai. It’s about training new mental habits very much like meditation, but in a way that’s accelerated and measured. But we’ve added the heart rate variability training because that brings in the body.

Heart coherence biofeedback is really about balancing the nervous system, the parasympathetic and sympathetic parts, but it’s also about bringing into harmony the brain and the heart.

Paola Telfer [00:33:57]:
Dr. Drew told me a story once about when he was doing some EEG readings on Zen monks and they were laughing because he thought they thought he’d forgotten the heart. The mind is so much more than the brain. The mind is also in the heart, in our bodies. And so we always train the heart as well.

Nick Urban [00:34:51]:
I find it’s the perfect start to a training session. I will do sometimes as little as 7 minutes of heart coherence training, and in just a few minutes, I can go about my day feeling completely leveled and clear headed.

Paola Telfer [00:35:26]:
It’s actually one of the most powerful aspects. It’s an immediate mood shift. And I would recommend 20 minutes. It puts you in a very different state. We are using the heart sensor throughout to optimize and personalize, which is what’s unique about Sens.ai compared to free breathing apps.

Dr. Drew Pierson [00:36:17]:
Typically, you want 4.5 to 7.5 breaths per minute, and it depends on your in and out. Everyone’s different.

Paola Telfer [00:36:34]:
What we’ll do is personalize it each time, but we’re also learning what your range is. So we’ll try and make it quite precise, like 5.25 or whatever it is. Right now, it’s always using the pulse oximeter.

Nick Urban [00:36:53]:
So let’s break down how exactly the system is working. You’re wearing a headset. You put a couple drops of water on the electrodes. You put it on, make it fit snugly, and then you choose a mission to train. What’s going on from there?

Paola Telfer [00:37:23]:
On the right cup, there’s a ground sensor. Really important to eliminate noise around you. On the left ear cup, there’s the pulse oximeter looking at the heart rate. And then on the blue part we call the flex cap, on top you’ll see the LED lights specialized for photobiomodulation.

Paola Telfer [00:38:00]:
Those are using 810 nanometer wavelengths. We do frequencies all the way from 1 Hertz to 1024 Hertz depending on what the program is. We talk about the functions as boost, train, and assess. Boost is the transcranial photobiomodulation sessions.

What’s unique is that because we have the electrodes, we’re able to look at the band and where you’re resonating. So if we’re boosting alpha, we can see you’re at 9 and a half today, or 10 and a half hertz today, not just stim 10 hertz blindly for everybody. Then we might stim you right on your resonance frequency, or tweak it up a little bit.

Paola Telfer [00:39:07]:
With alpha in particular, that feels really nice. It kinda gives you a nootropic effect. That’s the prepare boost. Train is the HRV training and neurofeedback training, and assess is a different thing.

Nick Urban [00:39:28]:
Those LEDs are very small. Can those actually cause a measurable shift in brain activity?

Paola Telfer [00:39:37]:
Yeah. 7 LEDs. It’s about 250 milliwatts per centimeter squared. And 1 Hertz to 1024 Hertz. We’ve been looking at that for about 4 years since we had working prototypes. What we found was a big difference in personalization. There’s people that we would stim at 10 Hertz that would have zero effect.

And we realized that once we read their frequency and then stim them there or higher, now we could actually see the entrainment on the EEG.

Nick Urban [00:40:33]:
You might not approve of this, but one thing I love about the boost mode is that you can put it on and go about other things while you’re still stationary.

Paola Telfer [00:40:54]:
You’re right. I don’t approve, Nick. But, we’re multitasking beings. Adding the meditation tracks to the boost will really help amplify the effects. The content is actually very important.

Dr. Drew Pierson [00:41:46]:
If you’re going to do something, I would read a physical book. Reading a paragraph will become easier during that time. But the meditations along with it are meant to bring the mind into intention about its attention.

Nick Urban [00:43:05]:
I have several other brain stim devices, and they can be powerful, but they’re definitely not customized or personalized to my current brain state. So I like that you guys have that baked in.

Dr. Drew Pierson [00:43:24]:
It was such a big feature to bring that about. Over time, your measurements may change and optimize. You’re not a stagnant being. You’re not a robot. Thank goodness.

Nick Urban [00:43:44]:
Why’d you guys choose to use light to stimulate the brain rather than isochronic tones, binaural beats, or haptic vibrations?

Dr. Drew Pierson [00:43:56]:
We tried a lot of things in the beginning. But photobiomodulation provides energy for the neurons. It can go directly into very specific areas of the brain. With binaural beats, you’re putting in information right into the ears, and a lot of people have auditory processing issues. The measurement came out like 20 or 30% effective for binaural beats.

With photobiomodulation, we can put exactly where we want and provide energy for those neurons. The ATP cycle kicks up, and you’re able to produce those frequencies.

Paola Telfer [00:44:58]:
It has the benefit of impacting the mitochondria directly and triggering that ATP cycle. Creating more oxygenation. And it’s also noninvasive. Even compared to other types of electrical or electromagnetic stimulation, light therapy is much more noninvasive.

Dr. Drew Pierson [00:45:38]:
In the brain, a big part of our operation is brain blood flow, the hemodynamic effects. It’s gonna increase blood flow and oxygen. It increases vascular health. These vascular cells are critical to maintain the blood brain barrier. Metabolically, we’re tapping into the stimulation of cytochrome c oxidase.

It’s a key enzyme in the mitochondrial respiratory chain. This leads to increased ATP or adenosine triphosphate production, the primary energy molecule in the cells.

Nick Urban [00:46:38]:
One other part of Sens.ai that caught my attention right off the bat, and it’s the reason I preordered it, was that you guys have a whole functional brain assessment module built in. Can you explain what that is?

Paola Telfer [00:46:58]:
When I first started looking at third party studies, I realized a lot of them were based on event related potential measurements, called ERPs. This is the standard methodology for measuring the speed of brain processing. When I looked at that, I thought, why couldn’t we just pull that into the headset? We wanted to be able to share people’s progress with them.

Paola Telfer [00:48:02]:
How am I gonna track actual progress? So we decided to add not just auditory ERPs but a visual component. We have that controller that looks like a Nintendo Switch. And what we’re able to measure is the speed of the brain processing during a task. The headset is actually measuring while you’re doing that test.

Paola Telfer [00:49:51]:
We can measure your accuracy, your reaction time, and even your recognition of when you’ve committed an error and then your adaptation to that. And we’ve done that to 1 millisecond precision, which is a bit of a technical feat.

Nick Urban [00:50:37]:
You guys are really gamifying all of this. By adding leaderboards, social leaderboards and personal leaderboards, you make it much more engaging and almost like a fun alternative to video games.

Nick Urban [00:51:24]:
One question I got from my community is how are you guys able to really personalize everything without a personal brain mapping?

Paola Telfer [00:51:49]:
A brain map is more clinical. The objective is to measure your brain activity as compared to an average. They’re comparing you to a database. What we’re training is very different. We’re trying to optimize you holistically. There’s a lot that can be seen in your brainwave patterns, heart rate variability patterns, and ERPs.

Dr. Drew Pierson [00:53:05]:
The surveys are very important. We’re doing brain maps at my office, but I’m looking for pathophysiology typically. It’s a difference between going to an Olympic training center and going to a rehab center. Ours is not medical based in that sense.

Paola Telfer [00:54:18]:
The other thing we’re doing that’s unique is we’re taking baselines across multiple sessions. We can do that because we’re at home with you, and we know it’s always you. That helps us know, are you having a good day? Can we nudge you further? Do we have to take it easy on you today?

Dr. Drew Pierson [00:56:00]:
The better you pay attention, your intention and attention during the session, which is meditation is really attention on a single thing. Most thoughts don’t interfere, but the more distracted you get, the less information you’re letting through because of that default mode network.

Paola Telfer [00:56:56]:
We can see the mind wandering in the spectrum. That baselining period takes that into account. We won’t hold you to the same standard as a monk. The system will be gentle when it can, and then nudge you when it thinks you can rise to the occasion.

Dr. Drew Pierson [00:58:17]:
Let’s say you’re just beginning. Get in a quiet environment. Learn these states. Once you’re adept, then you could start stepping into other things around you. If you can maintain your state during that, that’s the key. But build up slowly to that.

Paola Telfer [00:59:21]:
It’s gamified so it unlocks. At the me level, the self care level, after the assessment, missions will be recommended. It could be sleep based, brain fog based, attention based, or stress management. Generally, we’re creating a level of resilience. We’re doing a lot of alpha, beta, SMR training at that initial stage.

Until you’ve done the focus training, it’s gonna be very difficult to meditate.

Paola Telfer [01:01:31]:
Then there’s more layers on top, and now we start getting into mixes of the frequencies, but also synchrony. Getting all of those brainwaves, like different instruments in a symphony, to play the same song in synchronized timing. It starts to sound more beautiful and be more efficient as a system.

Paola Telfer [01:02:25]:
That’s why we took a systematic approach. We rethought the whole thing from first principles. We had really fresh eyes on it and just questioned all the assumptions. It’s not most efficacious for people to cherry pick programs as they go. There’s a more efficacious way.

Nick Urban [01:03:32]:
I found when I first started out, the calm training was incredibly frustrating because I expected that because I’ve been meditating for a decade that I would jump in and have an easy time. About 10 sessions in, I started getting the hang of calm, but then my very first focus session, I had it. It was very easy for me.

Paola Telfer [01:04:39]:
We’ve had so much good feedback on Deep Calm, which is just like a lower alpha, that we’re probably going to put it into the main star map so it’s available outside of the sleep mission.

Dr. Drew Pierson [01:05:03]:
It’s one of my favorite. Here in San Diego, you get out on a board and go surfing. When you’re done, you just have that deep calm, that flow. The dude setting, I call it. And that’s the same effect of the Deep Calm program.

Nick Urban [01:06:36]:
This is probably the best brain health, brain performance device I’ve ever come across. If someone wants to amplify the results, do you guys have any nootropic stacks or exercise modalities?

Dr. Drew Pierson [01:07:32]:
Nutrient wise, I have my go to’s. I use Wizard Sciences, the Neuro Rx, Utopia from BiOptimizers. Piracetam is my favorite. Omega threes, adaptogens, lion’s mane is huge at night for me, and creatine. And then the Chinese herbs. You start stacking those things, they work well. Get your sleep. Get your sun. Get your micronutrients.

The minerals are very essential too. Tried peptides before. Inflammation is shifted with BPC-157. I really like that in combination.

Nick Urban [01:09:06]:
Consistency, like the basics of health and wellness, they’re so important. If you’re not sleeping well, your neurofeedback isn’t gonna be nearly as effective. And then after that, as the final layer, you could add some nootropics and targeted nutrients.

Paola Telfer [01:09:33]:
We’re gonna have a community. Dr. Mark Atkinson and Dr. Drew Pierson are going to be running it. It’ll be called the Superconscious Collective, a place for conversations around supplements and everything else to help you optimize around the headset.

Nick Urban [01:10:20]:
The community aspect is gonna be huge. Are there any topics you feel are important to cover that we haven’t talked about yet?

Paola Telfer [01:10:37]:
We noticed a lot of folks in apartment buildings were having more EMF problems. We adapted for that. The EEG is this tiny microvolt signal. If we look at a double A battery at 1.5 volts, we’re looking at 500,000 times smaller. So for us to decipher that from eye blinks, EMF, a jaw clench, it’s a lot of digital signal processing.

We use wavelet math which is more precise on timing.

Paola Telfer [01:12:17]:
We decided early on that philosophically, we were going to be very transparent and never train noise. So we’ll just stop, we’ll tell you. Through that process, you’re learning that you can’t be chewing gum during this.

Paola Telfer [01:12:47]:
From a road map perspective, we’re really excited about rolling out group synchrony. That’s coming imminently. We’ll probably start with 2 people.

Nick Urban [01:13:49]:
How can people connect with you, follow your content and work, and pick up one of these devices?

Paola Telfer [01:14:03]:
Our name is the same as our URL. It’s sens.ai, written s e n s dot a i. That’s the best place to find us. We also have a YouTube channel and blogs that are quite in-depth.

Nick Urban [01:14:37]:
And I’ve done a couple reviews of this product. I did a written article and a YouTube video. Now if there was a worldwide burning of the books, and between the 2 of you, you get to save the works of 3 teachers. Who would you choose and why?

Paola Telfer [01:15:10]:
I think Nelson Mandela for the way he embodied leadership. Reconciliation versus retribution. Rudolf Steiner, who founded the Waldorf education system and contributed a lot to biodynamic agriculture and holistic medicine.

And Paramahansa Yogananda, who taught about divine truth transcending dogmas, about having heartfelt direct experience versus intellectual understanding of truth. And that’s really what we’re trying to bring forward with Sens.ai.

Nick Urban [01:17:00]:
Can you guys quickly run through the brain networks that Sens.ai trains?

Dr. Drew Pierson [01:17:08]:
We train along the center line. Technically, it’s a rich club network, 12 major networks that all combine. Default mode network, the salience network, and the executive networks are the 3 main ones, and those hit 80% of how we function.

As you start meditating and getting into alpha, we’ll notice alpha in the back of the brain, and then it moves forward as you progress. That creates a better bridge for synchrony and those exquisite states where you feel the top of the head kinda pop off.

Nick Urban [01:18:34]:
Let’s wrap up with one thing that the Sens.ai tribe doesn’t know about each of you.

Paola Telfer [01:18:43]:
As much as I love brain stuff, I also love mountain biking, skiing, hiking, paddle boarding, and recently started doing pickleball.

Dr. Drew Pierson [01:19:10]:
Chocolate is my passion. I’m a professional chocolatier, and next year I wanna become a master chocolatier. I wanna go to France and make some good chocolate. Dark chocolate. I want those flavonols. I combine them with Chinese herbs.

Nick Urban [01:19:41]:
It’s been a blast hosting you guys today. Are there any final thoughts or takeaways?

Paola Telfer [01:20:02]:
If people just want to take better care of their brain, there’s meditative practices with a lot of scientific backing. But very simply, breath work, and in particular, heart coherence practices. There’s a company called HeartMath that has a very inexpensive device that just does heart coherence.

That by itself can do a lot of wonders for your brain health and your nervous system. Just encourage people to take the first step there.

Nick Urban [01:21:39]:
Paola and Drew, thank you for joining me on the podcast. This has been a long time in the making. I’ve had great experiences so far. Thank you guys for creating an awesome product and making this more accessible to the world.

Paola Telfer [01:22:05]:
Thank you so much, Nick.
