Distinguishing REM sleep from other conscious states

(Medical Xpress)—Despite decades of research, little is known about the function of REM sleep, or the dreams that often accompany it. Rapid eye movements occur in most mammals, with a few exceptions like echidnas and dolphins. ...

Research shows how stress activates neurons that disrupt sleep

New research reveals that neurons in the preoptic hypothalamus—the region of the brain that regulates sleep and body temperature—are rhythmically activated during non-rapid eye movement sleep (NREM). Stress activates ...

Study finds we can respond to verbal stimuli while sleeping

Sleep is not a state in which we are completely isolated from our environment: while we sleep, we are capable of hearing and understanding words. These observations, the result of close collaboration between teams at Paris ...
