What does neuroscience tell us about voluntary movement? Why is the definition of "volition" so different from that of the legal definition of "intent"? Why are courts dismissing medically accepted mental health diagnoses? How can we draft better laws that are more scientifically based? What can recent advances in neuroscience tell us about the way we apply the law? This volume provides groundbreaking insights into the areas of scientific evidence and the intersection of neuroscience and law, and is the product of a collaboration by two experts in their respective fields. It is a primer for all those interested in neurolaw.
