Summary
Dr. Dan Sickler hosts Dr. Andrew Hill, founder of Peak Brain Institute and PhD in cognitive neuroscience from UCLA, for a deep dive into neurofeedback as a performance and wellness tool. Dr. Hill explains the full neurofeedback process: a quantitative EEG brain map measures electrical activity at rest with eyes open and closed, producing population-level comparisons that reveal outliers in theta, alpha, beta, and other frequency bands. He emphasizes that outliers are not automatically problems; the goal is to model what the data means for each individual and target changes based on personal goals rather than normalizing to average. The conversation covers the neuroscience of stress circuits, particularly the cingulate cortices. Dr. Hill explains that the posterior cingulate cramps up under stress and produces rumination and threat sensitivity, while the anterior cingulate produces perseveration and obsessive thinking when overactive. At their extremes, these patterns correspond to PTSD and OCD respectively, but Dr. Hill frames them as dysregulations of normal systems rather than diseases. He describes how neurofeedback trains these circuits by measuring activation and relaxation in real time and providing operant conditioning through visual and auditory feedback. Dr. Hill discusses the differences between biofeedback and neurofeedback, noting that all neurofeedback is a form of biofeedback but specifically targets the central nervous system inside bone. He explains why Peak Brain takes a personal training approach rather than a medical diagnosis model, comparing brain map outliers to lipid panels where context determines whether a value is concerning. The episode also covers COVID brain, the relationship between sleep, stress, and attention as interconnected brain resources, and the distinction between training high performers who have productive outliers versus correcting patterns that genuinely get in the way.
Key Points
- Quantitative EEG brain mapping measures electrical activity at 19+ scalp locations and compares results to population norms, revealing individual outliers in brainwave frequency bands
- Outliers on a brain map are not automatically problems; neurofeedback should train toward performance goals rather than normalizing everyone to average
- The cingulate cortices are key stress circuits: the posterior cingulate produces rumination and threat sensitivity when overactive, while the anterior cingulate produces perseveration and obsessive thinking
- Neurofeedback is a form of biofeedback that targets the central nervous system; it works through operant conditioning by measuring brain activation in real time and providing feedback
- Sleep, stress, and attention share overlapping brain resources, so improvements in one area through neurofeedback often cascade into the others
- Permanent changes typically require a few weeks of training to start experiencing subjective shifts and a couple of months for lasting modifications
- Peak Brain Institute takes a personal training approach rather than a diagnostic medical model, pairing brain maps with attention testing to set individualized goals
- COVID brain often shows up on brain maps as inflammatory markers and brain fog patterns that can be specifically targeted with neurofeedback protocols
Key Moments
Brain mapping reveals dysregulated cingulate circuits that drive anxiety and OCD
Dr. Andrew Hill describes how the cingulate cortices in the front and back midline of the brain switch focus internally and externally. When these circuits get stuck in high gear from stress, the posterior cingulate produces rumination and threat sensitivity while the anterior produces perseveration and obsession.
"the cingulates have sort of a corresponding relationship to switching your focus internally and externally. So the front midline helps you remember what you walked into the store for. And the back midline helps you go, ah, walk the road or heads up Frisbee and orient yourself to the important thing"
Neurofeedback is not diagnostic but treats dysregulation like a spasmed muscle
Dr. Hill reframes anxiety and OCD as dysregulation rather than disease. These conditions are not progressive, not caused by infection, and have no root cause to remove. They are more like a spasmed muscle or functional imbalance in strength, and like a whole system, they tend to respond to training.
"You don't really have to think about this as a disease. It's not a progressive process. It's not caused by something like an infection. It doesn't have a root cause where if you remove it, things go away. It's a dysregulation of a system closer to a spousal muscle or a functional imbalance in strength"
The brain picks up neurofeedback within five minutes of the first session
Dr. Hill's dissertation research showed that within about five minutes of a person's first neurofeedback session, the brain begins to notice and respond to the feedback. The key mechanism is that goals are constantly adjusted, and the brain learns involuntarily by having its frequency shifts applauded or de-emphasized by the computer.
"within five minutes, the brain is actually picking up the neurofeedback response. That was my dissertation work actually was doing a double blind placebo controlled study of neurofeedback with a 64 channel cap on top of it, looking at the evoked potential, trying to figure out how the brain was actually starting to notice the neurofeedback, like when it happened, how it was happening. In about five minutes, your very first session, the brain's like, hey, wait, what? Okay, that's being applauded. I'm going to react in that frequency."
A full dose of 40-50 sessions produces about one standard deviation of measurable change
Peak Brain maps the brain every other month during training, with 40-50 sessions being a full dose that tends to produce permanent changes. Most people see approximately one standard deviation of change on attention testing and brain mapping every 20-25 sessions.
"a lot of change. So we map every other month, every 20, 25 sessions at our office. And we end up getting something in the neighborhood for most people, something in the neighborhood of one standard deviation of change on their attention testing and their brain mapping every other month."
Showing people their brain maps removes shame and creates agency over mental health
Dr. Hill found that showing people their brain maps and explaining what is happening neurologically creates almost as much benefit as the neurofeedback itself. When clients see their anterior cingulate is crampy, they can reframe it as a superpower that has gotten dysregulated rather than a shameful disease.
"It created almost as much benefit as the transformation they got from neurofeedback. The agency that you understand, if you see your anterior cingulate is crampy and I can say, hey, that's the thing that shows up when you're a high powered CEO or if you have a little OCD, they can go, oh, okay, yeah, yeah. Cool, superpower, kryptonite, nice. Okay, get some control over that. And it's not a disease. Now it's like a quirk. It's a strength that's gotten a little dysregulated. And if you show people their brains and talk to them about what's going on, it creates this opportunity"
