title: [Impact of 36-hour sleep deprivation on visuo-motor coupling mechanism in young soldiers].
abstract: OBJECTIVE
  To explore the impact of 36-hour sleep deprivation (SD) on the brain electrophysiological 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 P500 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] and significantly increased reaction time [(632.5 ± 53.6) ms vs. (693.6 ± 65.7) ms, P < 0.05]. 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 P500 latencies 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-motor coupling in a certain extent. SD can affect the fixed position ability of visual space cognition in young soldiers.
