Thoughts on Thinking: The Physics and Biology of the Mind, by Shayne Heffernan

In the latest “Thoughts on Thinking” note, Shayne Heffernan shifts from how thinking is prompted to what remains when distractions fade. He frames a “driver” as the unresolved question and an “amplifier” as the environment and constraints that sharpen the answer. He argues that thinking isn’t a separate faculty over the body, but the body itself—specifically electrochemical activity across neuronal networks, including membrane potentials, inhibitory currents, neural rhythms, and metabolic state. He says measurable conditions can be moved to enter clearer states more reliably, withstand “load,” and recover faster after interruptions, noting work at KXCO aims to stabilize and make those conditions more inspectable.
