Gyorgy Buzsaki is one of the least appreciated and most profound neuroscientists alive. Like many proper philosophers, I think his understanding is best appreciated in conversation as opposed to via lectures or books. Though it is the case that his ~1982 review of hippocampal oscillations (which he basically codified) predicts a large majority of the concepts that neuroscientists that study sleep, learning, memory, and decision making are still trying to prove.
