New findings in neuroscience have given us unprecedented knowledge about the workings of the brain. Innovative research¿much of it based on neuroimaging results¿suggests not only treatments for neural disorders but also the possibility of increasingly precise and effective ways to predict, modify, and control behavior. In this book, Robert Blank examines the complex ethical and policy issues raised by our new capabilities of intervention in the brain. After surveying current knowledge about the brain, Blank discusses the political and philosophical implications of these scientific advances. If human individuality is simply a product of a network of manipulable nerve cell connections, and if aggressive behavior is a treatable biochemical condition, what happens to our conceptions of individual responsibility, autonomy, and free will?
