Mental rotation performance may be used as an index of mental slowing or bradyphrenia and may reflect speed of motor preparation. Previous studies suggest that major depressive disorder (MDD) presents correlates of impaired behavioral performance for mental rotation and psychomotor disturbance. Very little is known about the electrophysiological mechanism(More)
BACKGROUND Mental rotation performance may be used as an index of mental slowing or bradyphrenia, and may reflect, in particular, speed of motor preparation. Previous studies suggest depressive patients present the correlates of impaired behavioural performance for mental rotation and psychomotor disturbance. The aim of this study is to compare the mental(More)
OBJECTIVE To compare the mechanism of depressive disorder and schizophrenia' mental rotation ability so as to provide specific objective clinical indicators for identifying mental illness. METHODS Thirty depressive disorder (15 males, 15 females), 30 schizophrenia (15 males, 15 females) and 28 healthy participants (14 males, 14 females) were tested to(More)
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(More)
