Can you train your brain to improve your sleep, better your health, and possibly abolish your tolerance for alcohol, drugs, or other things you might be struggling with? According to today’s guest, Dr. Andrew Hill, peak performance coach and the founding director of Peak Brain Institute, one of the most insidious things about brain and mind-stuff is that we feel like things are not going to change, and that is just not true. The brain shift happens – it’s not a question of if, but how. Peak Brain Institute is a gym for your brain. It is a brain optimization company across life stages for some people. Neuroscientists help people take control of their own neuroscience the same way your favorite personal trainer at your gym helps you learn how to move through transformation goals. Also known as brain training, most forms of neurofeedback are a passive form of operant conditioning, but in an involuntary form. It’s essentially taking something you’re not usually aware of. For instance, they’re raising information from the brain waves or blood flow up to a level where the brain can interact with it. Dr. Hill emphasizes the use of the brain, not the mind. Hence, it’s different from the classic biofeedback techniques such as the use of relaxation therapy. Neurofeedback is an option for you to help with your brain, and studies show its positive impact on people dealing with issues pertaining to anxiety, stress, alcohol use, and drug use. On this episode, Dr. Hill talks about what’s going on and what’s happening in the brain as this process is unfolding so you can gain a better understanding of your brain, what makes up who you are, and how you can change or improve that. In this episode, you will hear: Biofeedback versus neurofeedback How your brain is trained to achieve your goals How brain mapping works The differences in results with eyes closed versus eyes opened The impact of brain training on physical fitness How neurofeedback impacts people with alcohol and substance issues Key Quotes: [04:46] “Neurofeedback is biofeedback, or a form of control, shaping, or exercise of stuff in your brain.” [04:55] – “All neurofeedback is a form of biofeedback, but not all forms of biofeedback are done in the brain.” [07:53] – “It’s mostly involuntary because you can’t feel your beta waves or your theta waves. But after about three or four sessions, you get this lingering effect that tends to show up for a couple of hours to about a day. It tends to impact the resources you have trained like your sleep, stress, and attention, and you get noticeable changes.” [10:00] – “Your brain is mostly an electrical and mechanical machine… and the resources of your brain are roughly the same.” [11:35] – “There are some things that emerge in the EEG that are almost diagnostic, or that are at least useful.” [21:41] – “Other brains with similar complaints and similar goals don’t respond the same way when you start doing neurofeedback. And so, you have to be very aware of the actual person’s experience.” [32:08] – “If you do a few weeks of neurofeedback, you abolish the tolerance for cannabis.” [39:21] “One of the most insidious things about brain and mind-stuff is that we feel like things are not going to change, and that is just not true.

Episode Summary
I sat down with Duane Osterlind on The Addicted Mind to walk through what neurofeedback actually does inside the brain, and how it changes sleep, focus, and your relationship with substances like alcohol and cannabis. You can watch the original conversation. What follows is drawn from that discussion, in my own words.
What is neurofeedback, and how is it different from biofeedback?
Neurofeedback is biofeedback done in the brain. All neurofeedback is biofeedback. Most biofeedback is not neurofeedback. You can warm your hands, track skin conductance, or train heart rate variability, and none of that touches the brain directly.
The reason the distinction matters comes down to awareness. Classic biofeedback and relaxation therapy work through the mind. You feel your breath slow, you feel your shoulders drop, and you steer it voluntarily. Neurofeedback works through the brain, and most of it is involuntary, because you cannot feel your brain waves. You cannot feel your beta. You cannot feel your theta. The brain has no sensory nerve endings inside it. When your head aches, the pain comes from the muscles, the meninges, the scalp, the skull, the tissue just outside.
So I take a signal you have no conscious access to, the electrical pattern of a specific circuit, and raise it to a level where the brain can interact with it. From there the brain does the work.
How does the brain get trained without you trying?
The mechanism is operant conditioning in an involuntary form. The first session most people do trains a frequency called SMR, sensorimotor rhythm. I measure a circuit on the right side of the brain involved in supervisory attention, the system that knows whether you are paying attention. Moment to moment, I watch how much theta and how much of a specific low-frequency beta wave you are producing.
When your brain makes a little less theta and a little more beta for half a second, the software responds. The game moves, the puzzle fills in, the sound plays. The brain notices something happened. A few seconds later the pattern drifts the other way, and the game stalls. The brain reaches for the reward again. Then I move the goalposts. Every few seconds the threshold tightens, so your brain has to trend across the session toward the target.
You cannot feel any of this in the first sitting, and most people do not. After three or four sessions you get a lingering effect that shows up for a couple of hours up to about a day. It lands on the resources you trained, usually sleep, stress, and attention. That is the point where people start telling me focus feels easier, like it takes less effort to hold. The video game only runs when the brain does the right thing for that day. The brain figures out that when it does this, stuff happens, and it carries that forward into the rest of your day.
This is a transient effect at first, like a workout. You feel the resource activate. We iterate gently upward over time. For more on training this specific rhythm, see SMR Neurofeedback: Train Sleep, Focus, and Self-Control.
What does a brain map actually show?
Before any training, I map the brain with QEEG, quantitative EEG. EEG is one of the oldest forms of neuroimaging. People were watching brain waves move reflected light off a rabbit cortex a century ago, before we understood what we were seeing.
Your brain is mostly an electrical and mechanical machine. Its resources stay roughly stable day to day and year to year compared to the average person your age. The amounts of your brain waves, the speeds of those waves, and the connectivity patterns between regions form a fingerprint that shifts slowly with development, learning, and injury.
I want to be honest about what mapping can and cannot do. Brain mapping has stayed mostly in the research space because most features are not diagnostic across people. There are trends and interesting phenotypes, but trying to call something a disorder because it is unusual falls apart once you try to make it discrete and diagnostic.
Here is a concrete example of why I stay cautious. In the 1980s and 1990s the research supported using the theta-to-beta ratio at the vertex to sort ADHD from non-ADHD kids, with high accuracy in early work. Replication studies through the following years kept getting weaker, and a later meta-analysis found the ratio no longer reliably separated groups (Arns et al., 2013). The likely explanation is that over that same window, the sleep status of America's youth collapsed, and you cannot distinguish ADHD markers from chronic sleep deprivation markers. They look the same on the data.
So I read maps as hypotheses, not verdicts. I add attention testing, which gives me clean, valid performance metrics against the average person. Then the map gives me eight to twelve features of your brain that are unusual, and we figure out together which ones get in your way, which are strengths, and which are noise. You validate the models. You tell me which ones are wrong, and usually ten to twenty percent of them are. If you want the full walkthrough, I cover it in QEEG Brain Mapping: What It Is, What It Shows, and What to Expect and Biohacking with EEG Phenotypes.
Why eyes closed versus eyes open?
We record two states. Eyes closed gives a cleaner data set, because the forehead relaxes and the visual system at the back of the head unloads. Eyes open activates more tissue but adds muscle and visual noise.
The contrast tells me something. If your eyes are closed but the back of your head keeps producing beta instead of relaxed alpha, that often points to a brain staying ready to process vision just in case, a hypervigilant pattern that struggles to disengage. If your eyes are open and you are still flooding the visual system with drifty alpha while your visual attention score is poor, that points toward inattention or fatigue. I check whether the system reacts the way I expect, and that gives me coarse features to test. Alpha patterns deserve their own explanation, which I give in Decoding Alpha Waves: Your Brain's Idle and Its Brakes.
Does brain training help the body too?
It does, and the direction surprises people. Train the brain top-down and physical fitness tends to come along. The athletes I coach make faster progress in strength, recovery, and skill acquisition when we train the brain alongside the body.
The metaphor I use: if you did curls for a few weeks, then later moved a rock out of the road, you would not stop to think about which muscles to fire. You would just move it and notice afterward that it was easy. When training lands on sleep, stress, and attention, the gains bleed into everything, because those are foundation resources. People come in half the time for symptoms and suffering and half the time for peak performance, and they tend to get both.
How does neurofeedback help with alcohol?
Alcohol has the longest history with neurofeedback, and the mechanism is clean enough to explain directly.
Anyone who knows a long-term drinker recognizes the wrung-out, shaky, overactivated state, the person who cannot settle, cannot turn the mind off, cannot fall asleep. Here is what is happening at the receptor level. GABA is the brain's primary inhibitory neurotransmitter after development, the molecule that makes circuits not fire. Glutamate is the excitatory one. They look like similar molecules, they bind to each other's receptors, and the brain holds them in very tight balance.
Alcohol is a powerful GABA enhancer. That is the calm, the sedation, the edge coming off. Push GABA too high and you pass out, which is why heavy drinking knocks you out. The body fights to rebalance by raising glutamate. Drink for years and the brain stops making its own GABA, leaning on the alcohol instead while glutamate climbs to compensate. Withdraw the alcohol and you are left with unopposed glutamate, an excitatory state the brain cannot inhibit. That is the seizure and cardiovascular risk of alcohol withdrawal.
The inhibitory tone that lets the brain relax and sit still is carried by SMR, sensorimotor rhythm. Picture a cat in a window, still body, laser focus on the birds. That is SMR. Train SMR up in a shaky, disinhibited brain and the body starts sleeping again, the brain starts generating its own GABA again, and the person gets comfortable with a quiet internal environment.
The protocol pairs two things. SMR mediates the overactivity and disinhibition. Then alpha-theta training brings GABA up deeply, taking you to the hypnagogic edge, that border of sleep where the conscious mind drops away and creativity surfaces. Together they re-educate the brain's deep downshift without needing alcohol to summon GABA. That combination changes people's relationship with alcohol whether they want moderation or abstinence.
The behavioral data is notable. The classic Peniston alpha-theta studies in alcohol-dependent veterans reported sharply lower relapse over long-term follow-up in the trained group compared to controls (Peniston & Kulkosky, 1989). Related work applying alpha-theta protocols in correctional settings reported lower reoffense rates as well (Quirk, 1995). My creative clients, actors, and athletes love alpha-theta too, because it opens flow-state access like a doorknob you can turn.
What about cannabis tolerance?
In what I see in the data, a few weeks of neurofeedback often cuts cannabis tolerance, and in heavy long-term users it can drop sharply. I have had decades-long users come back surprised, suddenly affected by amounts that used to do nothing.
The broader principle is about tolerance and reward. Anything stimulating, including non-drug rewards like food, television, or sex, needs moderation to stay in a good relationship with you. Extremes drive tolerance up and make the relationship slippery and stimulus-driven. Low, moderate use keeps tolerance where it belongs. When neurofeedback resets that tolerance, the brain stops needing escalating amounts to register the same reward. I explore the habit side of this in Biohacking Bad Habits: Upgrade Your Vices.
Can the brain repair alcohol damage years later?
Yes, and I see it in the data. Alcohol is the substance I worry about most. I see its signature decades after someone gets sober, while I do not see the same long-term damage from chronic stimulant use or even most polysubstance use when alcohol is not part of it.
The classic chronic-alcohol brain shows huge amounts of beta everywhere, an activated state, with hypercoherence, over-connected beta between regions that cannot let go, and low delta and alpha, meaning little capacity to downshift, relax, or sleep. It is a pattern I can often predict before I pull up the data.
About three months of training, roughly 40 to 50 sessions, can move that data substantially, get the person sleeping well, and support more stable activity. The seizure literature reports meaningful reductions with sensorimotor neurofeedback in people who had not responded to medication (Sterman & Egner, 2006). With alcohol-driven activity I see better than that, because the training addresses the drivers underneath.
Neurofeedback should not be the only thing you do. Substances reinforce their own learning. Find the path that fits you. If it is moderation, join moderation management and use the workbook. If it is abstinence, find what aligns for you. I am a strong fan of SMART Recovery and of mindfulness-based relapse prevention, which works like a CBT approach to dismantling triggers and automatic behaviors (Bowen et al., 2014). These are tools. Try one, and if it does not work, try another.
Struggling with change? The brain shifts more than you think.
If you are struggling, the most insidious belief about brain and mind problems is the sense that things will not change. The brain shifts. Resources get pinched and patterns get stuck, but very little of human experience is rigid or fixed.
There is a reason the feeling of permanence is so convincing. Your brain carries a negativity bias because the cost of missing danger is catastrophic. Miss a tiger once and the game is over. You can miss good things all day, because there is more tomorrow. So when you are depressed, in crisis, traumatized, or six beers into a night you did not plan to drink, your brain latches onto the moment as if it defines reality. It feels permanent. It is not.
Suffering in particular tends to move. You will always have an opportunity to lean in and make a small change. You might need other tools alongside it. The shift still happens.
