Have you read the books as well? I was wondering whether it's worth listening to the lectures or reading the book.

I read "Behave" and IIRC it covers around 80-90% of the lectures, moreover on the book you will find a couple of appendixes to refresh the reader on the basics of Biology and Neurology to better understand certain sections. I think that the lectures are a bit more entertaining than the book, but I found it more easy to follow than the lessons.
