*you can only do these helpful things well if you understand how perception works.

Neurons units of processing, relationship between nerve impulses & specific perceptions: everything in this course is based on, activity (firings, nerve impulses, action potentials) interconnections of neurons, neurons do(cid:374)(cid:859)t a(cid:272)tually touch ea(cid:272)h other!
