"Phantoms in the Brain: Human Nature and the Architecture of the Mind" by V. S. Ramachandran and Sandra Blakeslee
Ramachandran gets to the bottom of a lot of life's imponderables. Consciousness, identity, perception and the like. Some of the ideas Ramachanran deals with in this book can be found in the following papers, which can be freely downloaded as PDF files
"Synaesthesia - A Window Into Perception, Thought and Language"

"The Science of Art: A Neurological Theory of Aesthetic Experience"

"Three Laws of Qualia: What Neurology Tells Us about the Biological Functions of Consciousness, Qualia and the Self"
This body of work formed the basis for Ramachandran's 2003 BBC Reith Lectures.
You can listen to audio recordings of the lectures and download transcripts from the Reith Lectures site.
Broks seems a lot less certain than Ramachandran, in the capability of neuropsychology to provide answers to all the big questions of consciousness and the self. This is a position I feel a greater affinity with, despite a naive willingness to believe that such answers are possible.
This is the Guardian review of Paul Broks' book
