We All Have Brains That Are Weird Dr. Andrew Hill Peak Brain Institute

This conversation originally aired on the NeuroNoodle Neurofeedback Podcast, where I sat down with Jay Gunkelman and Pete Jansons. You can watch the original conversation. What follows is drawn from that discussion, in my own words.

What do I mean when I say every brain is weird?

After reading more than 25,000 brain maps, here is a pattern I trust: there is no normal brain to deviate from. Everyone is atypical. The map shows your specific configuration of activity across cortex, the regions that run hot, the regions that run quiet, the frequency bands that dominate where. When I sit with a client and show them their own QEEG, I am showing them how their particular brain is built and where it spends its energy.

That reframe matters clinically because the same measurement gets interpreted very differently depending on who walks through the door. I work with clients carrying acute, classic clinical presentations. I also work with the highest performers, people squeezing every drop out of life. And I find the same patterns across both groups.

Why does the same EEG pattern show up in high performers and in people with severe dysregulation?

Take the anterior cingulate cortex. This is a midline structure that handles conflict monitoring, error detection, and the sense that something is not right yet and needs attention. When the anterior cingulate runs hot, when it is metabolically and electrically overactive, you get a brain that keeps checking, keeps comparing, keeps flagging.

In one person that overactivity reads as perseveration, intrusive thoughts, the loops you see in OCD-type cortico-striatal patterns. The same person hates their own mind because it will not let go.

In another person the identical pattern reads as a highly effective executive. Organized, thorough, on top of every detail, and they love how their mind works. The anterior cingulate is doing the same job in both brains. What differs is how the rest of the system is wired around it, the person's history, their demands, and whether the trait is running them or they are running the trait.

What about back-midline activity and the threat response?

Consider activity along the posterior midline, the regions tied to vigilance and the body's threat-detection machinery. In one client that configuration is a trauma response. The system is over-allocated to scanning, the fight-or-flight circuitry sits on a hair trigger, and ordinary life keeps tripping the alarm.

In another client the same activity belongs to a highly skilled lifeguard. This person scans constantly, reads threat fast, and does not feel rattled by it. The vigilance is recruited, trained, and useful. They are not flooded by their own threat-detection because the regulatory circuits around it are doing their job.

Same map. Two outcomes. The phenotype on the page does not tell you whether the person is suffering. It tells you what their brain is allocated toward. This is why I lean on EEG phenotypes as descriptions of brain function rather than as diagnoses.

What is an endophenotype and why does it matter for brain training?

An endophenotype is a measurable, biologically rooted trait that sits between your genes and your behavior. In EEG terms, it is the stable signature in your brain map: where your alpha peaks, which regions carry excess slow activity, which run fast and tight. These patterns are more consistent than symptoms and they predict how your brain tends to operate.

Knowing yours gives you traction. If your anterior cingulate runs hot, you can train toward more flexibility instead of fighting your own checking behavior. If your vigilance circuits are over-allocated, you can train the regulatory side so the scanning stays useful without flooding you. Neurofeedback uses operant conditioning to shift these patterns, and your baseline map is the starting point that tells us what to aim at.

The evidence here is mixed by domain. That individual EEG signatures predict who responds to a given protocol is supported clinically and by work like Nan and colleagues on baseline EEG and training response. That a specific phenotype maps cleanly onto a specific life outcome is not established. That is the point of showing you the map: the pattern is real, the meaning is open.

How does this change the conversation in the clinic?

When I show someone their map, I frame it as here is what is different, would you like to work on it. That single shift changes everything about how a person engages with their own brain.

The clinical client and the peak performer are running variations of the same hardware. One has a configuration that is costing them. The other has a configuration that is paying off. Both can train. The trait does not get eliminated. It gets regulated, made voluntary instead of compulsory, tuned so it serves you rather than runs you. This is the core of self-regulation training and the reason I do not pathologize the patterns I see.

Your map shows a specific configuration, shaped by genetics and history, that is doing something. The question worth asking is what your brain is built to do, and whether you want to change how it spends its energy.

The next step is concrete: get your brain mapped, find out which of your traits are running hot or quiet, and decide which one you want to train first.
