THE PRACTICE
Understanding structure is one thing. Working with it directly is another.
Where the book maps the architecture of mind, the practice engages it — through brain mapping, neurofeedback, neuromodulation, and guided training. Not to fix what's broken, but to support what's trying to work.
THE GAP
Knowing what's wrong isn't the same as being able to change it.
You can understand exactly how your mind works and still find yourself unable to think clearly when it matters most. Scattered attention, emotional reactivity, mental fatigue, relational friction — these aren't failures of knowledge or motivation. They're limits of regulation.
The book makes the case that inner experience has structure. The practice is where that structure becomes something you can work with — not through interpretation or effort, but by engaging the systems that shape how thinking, feeling, and recovery actually unfold.
WHERE THIS IS PRACTICED
Peak Mind Neurotherapy
This work is practiced at Peak Mind Neurotherapy in San Francisco — a clinical practice focused on nervous system regulation and cognitive stability through QEEG-guided neurofeedback and neuromodulation.
James Croall, the author of The Quantified Soul, is a certified QEEG technologist and neurotherapy practitioner. The book's framework grew directly from this clinical work — from watching thinking break down and recover, session after session, in real time.
HOW IT WORKS
See it. Understand it. Train it.
01
Listen
It starts with attention — yours and ours. We begin by understanding what you're experiencing, what you've tried, and where thinking breaks down. No assumptions. No diagnostic labels applied prematurely.
02
Map
QEEG and ERP brain mapping reveals the syntax of your own mind — where rhythms coordinate, where they don't, and where regulation breaks down under load. Not what you're thinking, but how thinking is structured.
03
Train
Neurofeedback and neuromodulation work directly with the brain's own capacity to reorganize. Not forcing change — supporting conditions under which coherence becomes more reliable on its own.
The changes people describe are specific.
Steadier attention under pressure.
Faster recovery from stress and overwhelm.
More room between stimulus and response.
Clearer thinking in conversations that used to go sideways.
Sometimes the shift is subtle. Sometimes it changes everything.
A NOTE ON FIT
What this practice is — and isn't.
This is not talk therapy, coaching, performance optimization, or a diagnostic process. It's a supportive, adjunctive approach focused on regulation and capacity — working with the systems that shape thinking, not the stories about it.
It requires participation, patience, and respect for limits — both human and methodological. The aim is not transformation into someone else. It's restored flexibility: greater coherence and reliability within existing conditions.
For some people, reading and reflection are enough. For others, direct support makes sense. The distinction matters, and we'll help you figure out which applies.
Start with a conversation.
If you're curious whether this approach is right for you, we'll talk it through — no commitment, no pressure.
