The Brain on Trial

The past two decades have seen amazing advances in our understanding of how the brain functions. In particular, new and improved imaging technologies have inspired research studies that are designed to elucidate how brain structure and function relate to behavior. Not surprisingly, new findings in neuroscience are beginning to gain visibility in the legal system, including in the courtroom. In just the past few years, judges have been confronted with neuroscience-related issues like the maturity of the adolescent brain, states of consciousness, and the foibles of human memory. This symposium examines how one such issue, the connection between brain structure and function and violent behavior, could play out in criminal trials.

The session is formatted as a mock trial, with real attorneys, real neuroscientists, and a real judge. Prosecuting and defense attorneys call on neuroscience experts to offer testimony regarding neuroimaging of a fictitious defendant’s brain lesion.Sepcifically, the experts are asked to address whether the lesion left the defendant incapable of forming an intent to commit murder, thus making him not guilty of murder in the first degree. The two lawyers also offer legal arguments related to the standards for the admissibility of new technologies, personal responsibility, and whether the connection between brain imaging and behavior is reliable enough to be admitted as evidence in a criminal trial. And a judge discusses the factors that guide judicial decision making in cases like this.
