摘　　要：目的探讨36h睡眠剥夺(SD)对青年军人视觉-运动联结机制的影响。方法 10名健康青年军人在36h睡眠剥夺条件下,分别在SD前后进行视觉空间旋转任务的事件相关电位测定。测量P500的平均潜伏期、波幅及其错误数和反应时。结果与SD0h相比,SD36h错误率升高[(9.7±3.9)%比(18.3±4.5)%,P<0.05]、反应时延长[(632.5±53.6)ms比(693.6±65.7)ms,P<0.05],波幅降低[(8.7±2.3)μV比(5.2±1.6)μV,P<0.05]、潜伏期延迟[(489.6±42.6)ms比(530.2±51.9)ms,P<0.05],视觉空间旋转角度的典型线性(递增或减)函数消失。结论 36hSD在一定程度上损害了军人视觉-运动联结机制,从而损害视觉空间认知定位能力。Objective To explore the impact of 36-hour sleep deprivation （SD） on the brain electro- physiological indicators of visuo-motor coupling in young soldiers. Methods During the 36-hour SD, 10 healthy young soldiers were tested on visuospatial rotation tasks by event-related potentials system before and after SD. The incubation period and amplitude of PS00 as well as their error number and reaction time were measured. Results Compared with subjects in SD 0-hour, subjects in SD 36-hour had significantly increased error rate [ （9.7 ± 3.9） % vs. （ 18.3 ± 4.5 ） %, P 〈 0. 05 1 and significantly increased reaction time [ （ 632. 5 ± 53.6） ms vs. （693.6 ± 65.7） ms, P 〈 0. 051 ] Subjects in SD 36-hour showed significantly reduced amplitudes than those in SD 0-hour [ （8.7 ±2. 3 ） μV vs. （5.2 ± 1.6） μV, P 〈 0. 05 ] . Additionally, subjects in SD 36-hour showed significantly increased PS00 lateneies than did those in SD 0-hour [ （489. 6 ±42. 6） ms vs. （530. 2 ±51.9） ms, P 〈0. 05 ] . Compared with subjects in SD 0-hour, the deficit was an absence of a mental rotation function SD 36- hour in subjects. Conclusions The 36-hour SD in young soldiers can harm the processing mechanism of visuo-mo- tor coupling in a certain extent. SD can affect the fixed position ability of visual space cognition in young soldiers.
