REM and non-REM Sleep – controlling genes identified.

In Brain Science, Genetics, Sleep by Brainy Days Ahead

Prior research has identified genes that regulate the switch between wakefulness and sleep. This study conducted by researchers at the Peter O’Donnell Jr. Brain Institute identifies two genes fundamentally associated with sleep. One gene controls the amount of non-REM (rapid eye movement) sleep, including deep sleep. The other controls the amount of or need for REM sleep, which is associated with vivid dreaming.
