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.
