NEURAL BASIS OF SLEEP-DEPENDENT LEARNING AND DETERIORATION

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。测试纹理辨别任务中的睡眠依赖学习是否会增加视觉皮质视网膜区域的fMRI激活，以及午睡和夜间睡眠依赖学习是否会对这些fMRI反应产生同样的影响。测试纹理辨别任务的知觉退化是否与视觉皮质视网膜视皮层区域功能磁共振活动的减少相关。测试重复知觉测试后的表现下降和相应的fMRI失活是否可以通过富含SWS的一小时午睡恢复到基线水平。

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. Test whether sleep dependent learning on a texture discrimination task increases fMRI activation in retinotopic areas of visual cortex and that nap and nocturnal sleep dependent learning will have equal influences on these fMRI responses. Test whether perceptual deterioration on a texture discrimination task correlates with decreases in fMRI activation in retinotopic areas of visual cortex. Test whether decreases in performance and the corresponding fMRI deactivation after repeated perceptual testing can be restored to baseline levels by an hour nap rich in SWS.
