EmpowerHER reports that a portion of the brain may shrink when individuals do not get an adequate amount of sleep.


The cerebral cortex is the site of complex functions of the brain, and controls how we think and interact with the world. According to the study, lack of sleep may shrink part of the frontal cortex, which deals with problem-solving, self-control, planning and logic. Lack of sleep also accelerates the rate of brain loss in regions that process sound, language and spatial orientation.
