Sleep deprivation may be correlated with increased impulsivity and psychiatric disorders | Matthew Walker
The brain's amygdala governs our responses to fear, arousal, and emotional stimulation. Counter to the amygdala is the prefrontal cortex, which governs executive function and expression of appropriate social behavior. Poor sleep increases activity within the amygdala by impairing the normal inhibitory function of the prefrontal cortex. As such, sleep deprivation and poor sleep quality are inherently linked with many psychiatric disorders. In this clip, Dr. Matthew Walker describes how sleep impairs the opposing actions of the amygdala and prefrontal cortex to influence mood and mental health.
