The Dawn of Neuroscience
in America's Courtrooms

The Brain Defense combines true crime, brain science and courtroom drama. It raises profound questions about free will, criminal responsibility and our justice system.

“Excellent. . . . Davis’s book is sensitive to the moral and philosophical questions that hang over the legal battles he explores.”

—The Wall Street Journal

Brain Defense, murder, neuroscience, true crime

"A riveting journey down a new corridor in the American courthouse. An important book."


— Michael Connelly


“Davis is doing much more than giving Herbert Weinstein back his name and telling his complex story with compassion: He is reporting on a revolution taking place at the awkward intersection of brain science, technology and the law. . . . Davis’s book is sensitive to the moral and philosophical questions that hang over the legal battles he explores.
