I just ran across this absolutely terrific 2009 lecture series by Robert Sapolsky at Stanford. He has a real gift for discussing these topics, in depth, in a fun and memorable way.

Here’s the playlist.

UPDATE: when I originally posted this, I had only watched one of the later ones, where he applies the approaches of several disciplines to understanding a specific topic (eg depression, religiosity, schizophrenia). The ones nearer the beginning are reviews of those disciplines (neurobiology, evolutionary biology, etc) and are pretty skippable for people who already have a decent basic understanding of those topics. I’d suggest starting as I did with one of the later ones to see how you like it, and then watching whichever of the early videos you need an introduction to and jumping back to the second half.
