Mind Wide Open : Your Brain and the Neuroscience of Everyday Life
Johnson, Steven
Not quite as provocative as Emergence: The Connected Lives of Ants, Brains, Cities, and Software, this is still well worth your time if you have any interest in how your mind works. Johnson uses himself as guinea pig to explore what science and medicine have been learning about how the low level hardware of your brain works and how that might hook in to what passes for thought and consciousness.
