NEW BRAIN SCIENCE
What are the legal, ethical and moral implications of research in “the new brain sciences”? Rees and Rose, two distinguished British academics, invited the contributors to this collection of essays to ask hard questions about these subjects. Their answers will make you stop and think. You might hope, for example, that decades of progress in psychiatry and psychology would be helping courts assess guilt, innocence and appropriate punishments. But contributor Stephen Sedley, a British judge who spent six years presiding over homicide cases, finds experts to be of little value. He admires the jury system because “of the rapidity with which twelve lay people were generally able to grasp and apply to a live problem before them principles of law.” As for the testimony of psychiatrists, however, he says that he and the jury are typically left “peering into a very deep pool indeed with very little help about what was to be found there.” Perhaps the most visible of the new brain sciences is psychopharmacology, which has brought us drugs now taken by millions of people every day. John Cornwell, a historian of science at the University of Cambridge, writes from a courtroom in Louisville, Ky., describing a jury faced with “Prozac on trial.”
Weeks of neuroscientists’ testimony left them baffled when they had to decide the case of a workplace killer who was on the antidepressant. But it is the elementary schoolroom, not the courtroom, that is the scene of today’s largest-scale experiment in psychopharmacology. Over 2 percent of American schoolchildren now receive medication for attention-deficit hyperactivity disorder, writes Paul Cooper, a teacher and psychologist. “Medication should not be the default mode,” he notes, yet increasingly it is, and in many cases, the drug serves to “treat” children who merely “experience difficulty conforming to the kinds of behavioral expectations that are common in schools.” Yet these thorny issues pale next to vexing medical issues that the new brain research may raise. Readers are reminded that a neurologist won a Nobel Prize in 1949 for pioneering the lobotomy and that between the 1940s and 1960s surgeons cavalierly severed critical brain tissue in thousands of patients. Yadin Dudai, an Israeli neurobiologist, decries what he calls a new “lobotomy attitude” in neuroscience today, with researchers working toward “genetic manipulations, brain transplantations, even neurosilicon hybrids.” He counsels “humbleness and patience” in view of how little we yet understand.
