I got my brain mapped 🧠 Then took a nootropic and did it again a day later, and the results blew me away. It’s one thing to feel more mentally and cognitively sharp, but it’s a whole new story to have data showing the difference in brain activity. By the way, brain mapping can be a really neat tool for you to quantify how your brain may be getting in the way of your peak performance, whether it’s sleep issues, depression, ADHD, anxiety, some form of addiction or even PTSD. I recently visited Peak Brain Institute in LA for an interesting biohacking experiment — I wanted to know how a nootropic, “a limitless pill”, changed my baseline brain activity. Not only did I learn about both the ups and downs, but what’s even cooler, now I finally have quantified evidence how quickly, way above average, my brain processes information. All those brain hacks must be working 🧠 🤓 I’m super grateful for Dr. Andrew Hill, functional neuroscientist coach and founder of Peak Brain Institute, for taking the time to go over my brain and teach me how to make sense of it all. Thank you! The nootropic I tested was the Blue Cannatine from Troscriptions
Episode Summary
A guest came to Peak Brain Institute for an experiment I had not run quite this way before. She wanted to map her brain twice, one day apart, with a single variable changed between the two recordings: a nootropic. This conversation originally aired on Klaudia Balogh's channel, and you can watch the original conversation. What follows is my reading of the data, written in my own voice.
The compound she tested was Blue Cannatine from Troscriptions, a buccal troche combining methylene blue, CBD, caffeine, and nicotine. She took it the second day. Same room, same order of tasks, same eyes-closed-then-eyes-open recording protocol. One variable: a stimulant on board.
What does a QEEG brain map actually measure?
We put on a cap of electrodes, fill each site with conductive gel so the scalp signal reaches the amplifier, and record the electrical rhythms your cortex produces. Five minutes eyes closed, five minutes eyes open with your gaze fixed on one spot. That gives a resting baseline, your brain's idle, against age-matched population norms. If you want the full walkthrough of the procedure, I cover it in the QEEG brain mapping guide.
The map is a snapshot of how your circuits behave at rest. It tells you where the brain is over-allocating a frequency band and where it is under-recruiting one. Sleep trouble, anxiety, depression, ADHD, addiction patterns, PTSD: these show up in the data as specific spectral signatures, not as vague impressions. That is the value of mapping. You get a measurable picture of how your own brain may be getting in the way.
A note on test-retest. We do not expect a map to change meaningfully one day to the next. Your resting brain is rock solid the same two mornings in a row. So when something moves between baseline and nootropic, the substance moved it.
What did the attention test show before the nootropic?
Before we looked at brainwaves, she ran a continuous performance test twice: an attention measure and a stamina measure. The test has two sides. Attention is the gas pedal, clicking accurately on targets. Response control is the brake, withholding the click on the foil that follows a target. One is approach, the other is inhibitory tone.
Everything is age-matched against population curves. The mean is 100, with a 15-point standard deviation. Uncaffeinated, her full-scale attention score sat at 120, well above a standard deviation over average. Her visual and auditory scores spread apart slightly, which usually means a resource is being overused somewhere, though at that altitude it is hard to call.
Her visual reaction time was 157 on the test scale, and the raw speed was the standout. A late-teen athlete at peak conditioning registers visual information in roughly 70 milliseconds. The average twenty-year-old is closer to 90. The first 70 to 90 milliseconds is the signal arriving in cortex; everything after is the mind. Reacting at that floor is unusual fast. If you fast, manage stress, keep oxygenation high, you might shave into the 75-to-85 range. Hers was at the absurd end. Plenty of biohacking for intelligence points at exactly this kind of processing speed.
How did the nootropic change focus and stamina?
The troche sped her up. Full-scale attention climbed by 10 points, two-thirds of a standard deviation. That is not a practice effect and not a test-retest artifact; it is too large. Most of the gain was auditory. Visual attention rose about half a standard deviation, auditory rose a full 10 points. The compound filled an auditory bottleneck more than a visual one.
The brake side told the opposite story. Impulsivity went up, mostly because stamina collapsed. Her rock-solid baseline consistency tailed off toward the end of the task on both visual and auditory channels. Prudence stayed roughly the same, so this was not a strategy change; it was the raw resource fatiguing faster. Visual response control dropped from advantageous scores down to 104, still average, but no longer her standout.
This is the trade I see with stimulants generally. Speeding the system up biases the gas pedal up and the brake down. You get more attention and less inhibition in the same dose. If you struggle on the brake side at baseline, SMR neurofeedback trains exactly that inhibitory tone, and I unpack the speed-versus-control tension further in biohacking flow.
What did the brain maps reveal about mood and motivation?
Now the maps. Read alpha first. When alpha is high in the left front of the head, mood and approach motivation tend to sit low. This is the frontal alpha asymmetry literature, well-established as a marker of approach versus withdrawal. High left-frontal alpha looks like low engagement, a tendency to guard a resource rather than spend it.
On the nootropic, that left-frontal alpha dropped. The asymmetry shifted rightward, toward approach. In plain terms, the system flipped from protect-the-resource toward go-use-it. Jump in the car, go for the drive. Her mood signature looked better on the map, consistent with the engagement shift. If you want the deeper mechanism here, I wrote it up in decoding alpha waves and biohacking anxiety.
Why is auditory processing so sensitive in some brains?
The most interesting finding was not what the troche changed; it was what it did not. Behind both ears, over auditory cortex, the maps showed elevated theta and slow-wave activity in both recordings. The back right ran hot. The back right is where we plug the sensory world in, and when it runs hot I expect a particular profile: difficulty habituating to sound, sensory and social irritability, the princess-and-the-pea pattern where the car alarm two houses away gets in and stays in.
She confirmed it. Months living near a highway and still no habituation, even though the city brain next door tunes out a steady, non-changing roar within days. That is a built-in auditory quirk, present from the start rather than acquired, and it sat in the data regardless of the nootropic.
The troche made the auditory side worse over time. It shut down theta there but failed to bring the slow-wave delta up enough to wake the tissue, and her auditory stamina fatigued faster. So the stimulant that sharpened her overall focus also predicts more irritation with a roommate chewing, more trouble filtering competing voices on a group call. The sensory and social processing article covers this circuit in depth.
What is the overthinking marker on a brain map?
She mentioned a tendency to overanalyze. That usually lives at the anterior cingulate, the front midline. When the front midline runs hot in beta, I call it the OCD or CEO marker. It is the circuit behind songs stuck in your head and nail-biting, and also the circuit that builds companies and holds a vision with a steel grip. Hers showed the front-midline beta signature.
The nootropic unclenched it. Front-midline beta, the perseverative lock, dropped. The back-midline rumination signature dropped too. Both midline patterns went flat and flexible. Less stuck, less worried, less over-focused. The CBD content likely contributes to that relaxation alongside the stimulant lift. For the cortico-striatal mechanics underneath this, see biohacking OCD.
Reading the map as a system
Step back and the whole picture organized better on the nootropic. The top row of the analysis usually reflects metabolic issues, slow waves in the numerator. The middle row reflects executive function and filtering. The bottom row reflects anxiety. Across those rows the second map looked more broadly regulated.
There was a cost. Delta, the deep slow wave, dropped frontally. A lack of delta means the brain does not chill; it runs all-the-way-on or all-the-way-off. Fast waves decoupled a little in regions that normally run locked together, which buys flexibility but also explains the faster fatigue. More engaged, more flexible, less stuck, and burning the resource quicker. That is the full ledger, not just the upside.
What can you actually do with this?
A nootropic is one lever, and reading it against your own baseline tells you whether it helps you or fights your wiring. For this brain, the compound helped mood, engagement, and overall focus, and it cost auditory processing and stamina. Someone with a clean auditory cortex and weak inhibition would get a different ledger entirely. That is the point of mapping before you optimize.
The durable changes do not come from a troche. They come from training the circuits the map identifies. If the brake side is weak, you train inhibitory rhythms. If auditory cortex cannot habituate, you work on that integration directly. Neurofeedback is the tool for moving a resting baseline rather than borrowing a state for a few hours.
One more observation from the clinic that has stayed with me. The brains I have mapped in people recovering from COVID often look like they had a concussion. Same kind of slow-wave signature, same kind of disrupted regulation. That is clinical observation, not a controlled finding, and it is worth more study.
If you want to know why you cannot sleep, why you ruminate, why your focus fails on the brake side, the answer is in your own spectral data. Map first. Then decide what to change.
