WSU: The Biology of Consciousness with Christof Koch

TL;DR

Delving into the enigma of consciousness through neuroscience and philosophy, exploring its origins and implications.

Transcript

right so we heard a lot about very beautiful data about observational astronomy and cosmology so now we're turning from the mind of course behind all the data is in a mind the mind of the human observer that peers out at the universe and wonders at how the universe came about so what we're now going to do in the next hour we'll turn that those tele...
