Abstract
The intensity of the visuo-vestibular interaction, i.e., visuovestibular
conflict, would influence upward self-motion and downward selfmotion
latencies and cardiovascular activity. In order to test this hypothesis,
thirty five healthy adults aged 22 years in average have been immersed to
a central visual motion via a HMD. During upward and downward selfmotion
perception, the engagement of vestibular saccular organs seems to
contribute differently to latencies and cardiovascular activation depending
on the direction of gravitational acceleration. Downward selfmotion
latencies (same direction acceleration) are shorter than upward self-motion
latencies (opposite direction acceleration). In the same vein, cardiovascular
autonomic activation, reflecting by heart rate, is lower for downward selfmotion
than for upward self-motion. Our results provide evidence that
visuo-vestibular interaction would contribute to influence both latencies and
cardiovascular variation in vertical self-motion perception.
