I highly recommend this book by Kevin Davis, The Brain Defense: Murder in Manhattan and The Dawn of Neuroscience in America's Courtrooms.
This image conveys much of what it's about:
This is my endorsement, which appears on the back cover:
The Brain Defense is a stirring ride into a fascinating new field. Can a tumor or traumatic brain injury explain rape or murder? Can they diminish culpability? If your instinct screams no, read page one. The first staggering case will challenge your assumptions; the book that follows may alter them permanently. The vividness and urgency of Kevin Davis’s storytelling, along with his artful touch, draw you in from the first line, and never let you go.
