Coriolis Illusion

The Coriolis illusion, also known in psychophysical perception as the Coriolis effect or the vestibular Coriolis effect, is the misperception of one own body orientation that occurs when the head is tilted forward or backward while the body is rotating, often producing dizziness or nausea. The illusion arises because head movement during a spin stimulates the semicircular canals of the vestibular system in a way that conflicts with the visual sense of body position, and equilibrium returns only once the head comes back to a stable position. A related pseudo-Coriolis effect can occur from visual rotation alone, with no actual physical spinning, producing the same sensation of self motion and the same kind of nausea.
