title: To dream or not to dream? Relevant data from new neuroimaging and electrophysiological studies.
abstract: The study of sleep and dreams has enjoyed a major breakthrough with recent findings from brain imaging studies in humans. Several independent groups have shown global deactivation of the brain during non rapid eye movement sleep and a regionally selective reactivation during rapid eye movement sleep. These results are complemented by new brain lesion and electrophysiological recording data to give a detailed picture of the brain dynamics of changes in conscious state.
