which functional brain area is activated during rem sleep (where we dream)
Rapid eye movement sleep Research in the 1990s using positron emission tomography (PET) confirmed the role of the brain stem and suggested that, within the forebrain, the limbic and paralimbic systems showed more activation than other areas.[1] The areas activated during REM sleep are approximately inverse to those activated during non-REM sleep[10] and display greater activity than in quiet waking. The "anterior paralimbic REM activation area" (APRA) includes areas linked with emotion, memory, fear and sex, and may thus relate to the experience of dreaming during REMS.[9][15] More recent PET research has indicated that the distribution of brain activity during REM sleep varies in correspondence with the type of activity seen in the prior period of wakefulness.[1]
Sleep Sleep is divided into two broad types: non-rapid eye movement (non-REM or NREM sleep) and rapid eye movement (REM sleep). non-REM and REM sleep are so different that physiologists identify them as distinct behavioral states. Non-REM sleep occurs first and after a transitional period is called slow wave sleep or deep sleep. During this phase, body temperature and heart rate fall, and the brain uses less energy.[5] REM sleep (also known as paradoxical sleep), a smaller portion of total sleep time and the main occasion for dreams (or nightmares), is associated with desynchronized and fast brain waves, eye movements, loss of muscle tone,[1] and suspension of homeostasis.[11]
