Two weeks ago I gave a talk on my book at the American Scientific Affiliation meeting at Azusa Pacific. Since the theme of the meeting was the mind and brain sciences, I focused on the chemistry of the brain and why I think that chemistry would be similar on different planets. This is an extension of Chapters 9 and 10 of my book with some new research findings.
Here's the audio for the talk*, and here's a PDF of the slides (fair use pics only).
