- The aim of this experiment is to identify the relationship between human cardiovascular responses and tilt perception during rotation on a short radius centrifuge. The assumption is that cardiovascular changes during centrifugation are dependent on cortical structures that integrate graviceptives information at the cognitive level. Recent studies have shown that heart rate and blood pressure increase in people who have the illusion of moving from lying to standing position (through a virtual reality device), while they are actually in a lying position.

During centrifugation on a short radius centrifuge, the perception of inclination varies from one subject to another because of their morphology and the gravity gradient. Indeed, the centrifugal force at the otolith organs of the inner ear is lower than in the visceral organs or soles. The purpose of this experiment is to find a position on the centrifuge for which every subject report the same inclination feeling.
