Science Blog - The (brain) stuff of which dreams are made
"A grand tradition in the study of the brain is to wait for disaster to strike. The functional map of the brain--identifying which areas underlie movement, different senses or emotions, memory, and so on--has largely been filled in by observing which functions were eliminated or changed with injuries or strokes to focal areas of the brain. In a new study, scientists describe a patient who lost all dreaming, and very little else, following a stroke in one distinct region of the brain, suggesting that this area is crucial for the generation of dreams."
