Abstract : The vestibulo-ocular reflex (VOR) and spatial orientation perceptions were recorded in 15 subjects during a 3 Cz centrifuge run. These data were obtained to study two issues; first, to gain insight into reports of asymmetrical disorientation and disturbance during acceleration and deceleration of C-induced loss of consciousness (C-LOC) training centrifuges. Second, to study the effects of sustained vertical linear acceleration on the vestibular system. The centrifuge run consisted of an acceleration to 3 Gz in 19 s, sustained 3 Gz for 5 min, and a deceleration to 1 Cz in 19 s. The runs were repeated three times with the subject facing the motion, and three times with the subject's back to the motion. The VOR and spatial orientation perceptions from the eight subjects who completed all six runs were analyzed.
