Thought, learning, perception, reasoning, and language are all cognitive abilities powered by the soft squishy gray stuff inside our skulls. After a quick-and-dirty introduction to neurons and the brain, we'll examine several aspects of human cognition and look at the neurophysiology that underlies them. We'll also discuss methods used to study these areas, read some current research, and navigate the wilds of the science library.
