The Spike Quotes

“The uniquely human things you do are thanks to the chatter of spikes in your cortex. This outer layer of the brain contains more neurons in you than in any other animal, ever. So many in fact that we have to divide the cortex into a constellation of areas, each with its own name, to make sense of it all. (Few of these names are exciting—the area with the most neurons that talk directly to the spine, and so has the most control over movement, is called the primary motor cortex; the areas next door are the premotor cortex and, wait for it, the supplementary motor area. Inspired.) These areas all share the same types of neurons but do wildly different things with the spikes sent between them.”
