This volume contains the proceedings of a two-day multidisciplinary conference on the ethical implications of brain research organized by Stanford University and the University of California, San Francisco. Leaders in neuroscience, journalism, law, and philosophy, among other fields, engaged in a freewheeling debate on the social and individual effects of the research. Steven Marcus has edited their formal and informal deliberations to present a compelling first-hand account of the proceedings, providing a highly readable front-row seat about the first-ever symposium on neuroethics.
