Each one stands alone — start wherever the topic pulls you.
How your brain knows where you are: place cells, grid cells, head-direction cells, and speed cells, built into an interactive tour of your built-in GPS.
Seven reflex circuits from knee-jerk to gag — the shortcuts your nervous system uses to keep you alive.
How neurons talk to each other in molecules: dopamine, serotonin, glutamate, GABA, and the receptor twist that turns a signal into a feeling.
Delta, theta, alpha, beta, gamma, splines, and the rhythms beyond the cortex — how the brain keeps time with itself.
Eighty-six billion neurons renegotiating their friendships every second: Hebb's rule, spike-timing plasticity, and a small trainable network.
Nine senses that almost never get a name — vestibular, proprioception, interoception, nociception, and more.
Electricity, magnetism, sound, light, touch, rhythm, and genetic switches — for clinicians and the patients they explain them to.
