研究了在声节奏节奏力产生过程中，睡眠剥夺对脑活动脑磁图成像的事件相关场和功率分布的影响。在行为水平上，在较高的运动速度下，SD减少了产生的力和声刺激之间的滞后（负异步）。脑磁图的主成分分析显示，SD后，听觉和运动诱发的脑区减弱，并显示能量向更多的额叶通道前移。这些结果被解释为传入感觉输入的中枢加工因SD而改变。2005爱思唯尔爱尔兰有限公司版权所有。
The influence of sleep deprivation (SD) on event-related fields and the distribution of power over the scalp of MEG imaged brain activity was studied during acoustically paced rhythmic force production. At the behavioral level, SD resulted in a reduction of the lag (negative asynchrony) between produced forces and acoustic stimuli at higher movement tempos. Principal component analysis of the accompanying MEG activity showed that auditory- and motor-evoked fields were attenuated after SD and revealed an anterior shift of power towards more frontal channels. These results were interpreted in terms of a change of central processing of afferent sensory input due to SD. (C) 2005 Elsevier Ireland Ltd. All rights reserved.
