BIOS Instant Notes in Neuroscience [PDF ebook] 

BIOS Instant Notes in Neuroscience, 3rd edition, has been reorganized and some detail removed from both text and figures in order to make it a more effective resource for students. While concentrating on core themes, areas where there have been significant advances, especially learning, memory, and cognition, have been thoroughly updated. There will be a separate section on methods allowing students to separate results from methodology.
