Another discounted book from the corner store. Written by McGaugh with a quote from Sapolsky on the cover and a quote from LeDoux on the back? It's practically required that I read this.

It's a very interesting book. It is intended for the layman, but there are sections where McGaugh goes on at length about different neurotransmitters (catecholamine, GABA, etc.) that can be a little intimidating. The list isn't there because you need to understand the details, though--it's there because you need to understand the complexity of the system, the excitatory vs. inhibitory effects of various neurotransmitters, and how isolating different neurotransmitters allowed researchers to confirm the importance of certain brain regions.
McGaugh is a giant in the field of learning & memory, so it's great to read this summary from one of the most important researchers in the field.
Although as a scientist McGaugh is unwilling to go out on any limbs and make any recommendations about how you should change your life in light of this research, I'll go there: study and practice before bed, go to sleep at a reasonable hour, and get a good night's rest. Sleep, the book suggests, is particularly important for memory consolidation.
