Johns Hopkins researchers have found strong evidence supporting the view that the sleeping mind functions the same as the waking mind -- a discovery that could significantly alter basic understanding of the normal and abnormal brain. The evidence comes from a study, to appear online this month in the journal Human Brain Mapping, of 11 healthy male and female participants whose rapid eye movements (REM) in "dream" sleep were timed using a video camera. The REM tracking was accompanied by special MRI images designed to visualize brain activity.
