For this two-parter, which concludes next Wednesday, Chedd and Alan Alda create a fictional trial of a teenager accused of attempted murder. As the trial unfolds, Alda talks to neuroscientists and legal experts about brain scanning techniques that decode emotions, thoughts, and memories, and the role they could play in the courtroom. Is neuroscience the future of the law?
