"Neurolaw"

My daughter, who is a neuroscience major, pointed out this article in yesterday's New York Times Magazine. It discusses how the ability to perform PET scans, MRIs and other tests on the brain may affect the law. If we can see that a defendant's brain is abnormal, what happens to the legal system's concept of responsibility for criminal acts? The article was written by Jeffrey Rosen, who is on the faculty of the George Washington University Law School, where he teaches constitutional law and criminal procedure.
