When these cells become injured or diseased, people do not experience the muscle paralysis associated with REM sleep, which can lead to REM sleep behavior disorder-a serious condition in which the afflicted violently act out their dreams. We do know that a small group of cells in the brain stem, called the subcoeruleus nucleus, controls REM sleep. The purpose of REM sleep remains a biological mystery, despite our growing understanding of its biochemistry and neurobiology. This mode is bizarre: a dreamer's brain becomes highly active while the body's muscles are paralyzed, and breathing and heart rate become erratic. When these cells switch on, it triggers a loss of consciousness.Īfter SWS, REM sleep begins. Scientists now have concrete evidence that two groups of cells-the ventrolateral preoptic nucleus in the hypothalamus and the parafacial zone in the brain stem-are involved in prompting SWS.

The brain generates two distinct types of sleep-slow-wave sleep (SWS), known as deep sleep, and rapid eye movement (REM), also called dreaming sleep. Sleeping is an integral part of our life, and as research shows, it is incredibly complex. It even plays vital roles in regulating mood, appetite and libido. Sleep serves to reenergize the body's cells, clear waste from the brain, and support learning and memory. The function of sleep has mystified scientists for thousands of years, but modern research is providing new clues about what it does for both the mind and body. Murray, director of the sleep laboratory at the Sunnybrook Health Sciences Center, respond: Turn it off and get the rest.John Peever, director of the Systems Neurobiology Laboratory at the University of Toronto, and Brian J.
