Cognition impairment caused by space motion sickness often is a risk of spaceflight. So the dynamic changes of pattern of brain cognitive processing under varied vestibular stimuli was explored using event-related potentials. Vestibular stimulation was produced by rotary chair and varied linearly, i.e. control, constant 10 degrees/s rotation and constant 0.6 degrees/s, 0.8 degrees/s, 1.0 degrees/s, 1.2 degrees/s acceleration. Thirty-three subjects participated in the study and performed same auditory selective attention task in which the odd numbers in a randomly mixed series of odd and even numbers (go/no-go) presented acoustically in Chinese pronunciation were assigned as target signal during the rotation stimuli...
