 Coriolis effect (perception)

In psychophysical perception, the Coriolis effect (also referred to as the Coriolis illusion) is the misperception of body orientation and induced nausea due to the Coriolis force.This effect comes about as the head is moved in contrary or similar motion with the body during the time of a spin, this rotation of the head affects the semicircular canals within the ear which causes a sense of dizziness or nausea before equilibrium is restored after the head returns to a stabilized state.
