Lawyers are increasingly relying upon advances in neuroscience in their practices, such as establishing whether or not a litigant is competent to stand trial or sign a contract, determining if the memory of a witness is accurate and reliable, deciding how best to represent a client with an addiction, or convincing a jury that an offender was capable (or not) of controlling his violent behavior.  Advances in neuroscience are helping scientists better understand how the brain  functions, and it is now, more than ever, vitally important that lawyers comprehend these advancements in order to successfully represent their clients.
