Research on effect of sleep deprivation on cognitive brain function / 生物医学工程学杂志

ABSTRACT

Research on the effect of sleep deprivation (SD) is an approach to shedding light on the working mechanism of sleep for cognitive brain function. To explore how SD affects cognitive function, a number of measures involving psychology, brain imaging and electrophysiology, have been adopted in this area. Research groups from domestic and verseas have focused on many aspects of cognitive science and have acquired initial results, but uniform conclusion has not been made because of mixed factors. Starting from the mechanism of SD, this paper summarizes the progress in the search of effect of SD, including the neurophysiologic change by brain imaging and the use of EEG for evaluating the decline of cognitive function, and then analyzes the main influential factors and orientation of future research in this area.
