睡眠剥夺对面孔情绪加工的影响OA

Facial expressions are an important form of social interaction and emotional contagion,and accurate facial emotion pro-cessing helps to generate appropriate social behaviors.Sleep deprivation can affect different aspects of facial emotion processing,impai-ring facial emotion categorization,blurring emotional ratings,and reducing memory consolidation.Previous research has provided direct or indirect evidence for the role of whole-night sleep,rapid eye movement(REM)sleep,and non-rapid eye movement(NREM)sleep in facial emotion processing through different types of deprivation manipulations.Based on existing evidence,it is suggested that abnor-mal facial emotion processing may be REM-dependent,reflected in the activity of the amygdala,prefrontal cortex,insula,and anterior cingulate cortex,as well as nocturnal changes in gamma and theta oscillations.Further exploration of the mechanisms involving sleep stages or their combination in facial emotion processing is needed,which may lead to the diagnosis of sleep-related disorders and pre-diction of treatment efficacy based on facial emotion processing.
