COGNITIVE PERFORMANCE FOLLOWING TOTAL SLEEP DEPRIVATION

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得主要资金，因此可以在其他CRISP条目中表示。所列机构为中心，不一定是研究者所在机构。研究神经生理学因素，使某些人表现出对睡眠不足的不利影响的相对抵抗力，并在不同难度的任务中探索这种抵抗力。研究自然表现出不同睡眠需求的两组受试者的认知表现和大脑激活差异：习惯性长睡眠者和习惯性短睡眠者，并在独立执行的同伴研究中与正常对照组进行进一步比较。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Investigate the neurophysiological factors that allow certain individuals to show a relative resistance to the detrimental effects of sleep loss and to explore this resistance across tasks of varying degrees of difficulty. Examine cognitive performance and cerebral activation differences in two groups of subjects who naturally show a differential need for sleep: habitual long-sleepers and habitual short-sleepers, with further comparisons to normal controls in an independently executed companion study.
