Until now decision-making has been studied in the fields of psychology, artificial intelligence, and economics - to name just a few - while neuroscientific research has paid only little attention to it. But now the importance of decision-making has become indisputable, especially in the context of reasoning processes that culminate in the personal and social decisions that define rationality. This book contains articles by leading researchers in experimental neuroanatomy, neurophysiology, neuropsychology, neurochemistry, neurocomputation, experimental psychology, and philosophy, discussing the contributions made by these disciplines to the emerging field of neurobiology of decision-making.
