The Effect Of Sleep On The Regulation Of Emotional...

Introduction The goal of this study was to investigate the role of sleep in the regulation of emotional reactivity and mood, and in particular the role of rapid eye movement (REM) sleep. The research team led by Rosales-Lagarde measured the impact of total sleep deprivation (TSD) by evaluating subjective responses to frustration and aversive stimuli. It was found that coping skills and emotional regulatory abilities were decreased along with decision-making skills following REM sleep disturbances. It was also found that the subjects that experienced disturbances in REM sleep displayed a greater degree of impulsiveness when faced with a risky decision and favored utilitarian judgments. The data was collected using functional magnetic resonance imaging (fMRI) imaging of the brain during the various stages of the experiment, and during the administration of the Emotional Reactivity Task. It was found that there is a greater and longer lasting activation of the amygdala while viewing negative stimul i, and specifically following TSD. This study was based on previous research that suggests that REM sleep plays a significant role in emotional regulation, as brain areas associated with emotion are specifically activated during REM sleep cycles. These include the amygdaloid complex, medial and orbital frontal cortices, and posterior association areas.
