How are are breakthroughs in neuroscience and new technologies such as brain scans being used in today's courts to judge guilt and calculate punishment? Professor Denno explores important criminal justice issues from the lens of modern neuroscience and explains the extent that evolving scientific insight is affecting the criminal justice system.
