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 underlying this deficit.

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.
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 rotation abilities of patients with a first episode of depression, recurrent depression and healthy control subjects with regard to hand tasks.

Article Synopsis
- - The study compares how individuals with depressive disorder and schizophrenia perform on mental rotation tasks using letters, aiming to find specific clinical indicators for these mental illnesses.
- - Results showed that those with depressive disorder had a higher error rate for normal letters but a lower error rate for mirror images, while individuals with schizophrenia had a lower error rate for normal letters but a higher error rate for mirror images.
- - Overall, depressive disorder significantly impairs overall mental rotation ability, whereas schizophrenia shows a distinct pattern of impairment, highlighting differences in their cognitive profiles.
