Special Issue Information

Dear Colleagues,

Sleep is essential for maintaining behavioral performance and well-being in daily life. It is evident that inadequate sleep adversely affects people’s cognitive and affective functions, such as attention, memory, emotion, and social interaction. Moreover, sleep loss affects individuals’ brain functions, including the thalamus, default mode network, and frontal–parietal attention network. However, sleep loss commonly happens in modern society. The effect of sleep loss was documented in many contexts, such as at work and educational environments, in traffic safety and in public health. Therefore, it is crucial to increase the scientific understanding of how sleep loss affects people’s performance and brain function.

This Special Issue plans to provide an overview of the recent advances related to sleep loss on human behavioral performance and neural activity. Research and reviews related to sleep deprivation, sleep restriction and sleep disorders (e.g., insomnia) are welcome.

Abstract

Sleep deprivation leads to reduced inhibitory control in individuals. However, the underlying neural mechanisms are poorly understood. Accordingly, this study aimed to investigate the effects of total sleep deprivation (TSD) on inhibitory control and their neuroelectrophysiological mechanisms from the perspective of the time course of cognitive processing and brain network connectivity, using event-related potential (ERP) and resting-state functional connectivity techniques. Twenty-five healthy male participants underwent 36 h of TSD (36-h TSD), completing Go/NoGo tasks and resting-state data acquisition before and after TSD; their behavioral and electroencephalogram data were recorded. Compared to baseline, participants’ false alarms for NoGo stimuli increased significantly (t = −4.187, p < 0.001) after 36-h TSD. ERP results indicated that NoGo-N2 negative amplitude increased and latency was prolonged (t = 4.850, p < 0.001; t = −3.178, p < 0.01), and NoGo-P3 amplitude significantly decreased and latency was prolonged (t = 5.104, p < 0.001; t = −2.382, p < 0.05) after 36-h TSD. Functional connectivity analysis showed that the connectivity of the default mode and visual networks in the high alpha band was significantly reduced after TSD (t = 2.500, p = 0.030). Overall, the results suggest that the negative amplitude increase in N2 after 36-h TSD may reveal that more attention and cognitive resources are invested after TSD; the significant decrease in P3 amplitude may indicate the impairment of advanced cognitive processing. Further functional connectivity analysis indicated impairment of the brain’s default mode network and visual information processing after TSD. Full article
