The entire body is ‘brain’ and more… than brain… for we do not have concepts that are anything like our anatomy yet, except in the most crude, reductive and mechanical ways…

This has been obvious to me since I was 7.

“The nervous system of animals without brains is a knotted network of neurons connected together and cast throughout their body. Often neurons are wadded together and stashed next to the body structures they operate, such as the bunches of neurons clustered like grapes next to each segment of a lobster’s articulated tail A similar neuroanatomy is true of people, but human beings with their emphasis on conscious intellectual functions easily overlook this and assume that the brain does it all.”
