One of the science blogs I'm really enjoying in my Google Reader is called Neuroanthropology by Daniel Lende and Greg Downey (their Wednesday roundup of links to research and stories is particularly useful). They brought my attention to these lectures on human behavorial biology by Stanford professor of biology and neurology, Robert M. Sapolsky, author of Why Zebras Don't Get Ulcers.
I just watched the hour-long intro to neuroscience, taught by very able grad students, to prepare the class for Sapolsky's lectures in his spring, 2010 class on human behavorial biology. The intro to neuroscience is a bit technical, but pretty much presented in basic English for beginners. I especially like the student-produced rap video at the end of the presentation about how synapses work.
