Purkinje's law of vertigo

Related people

This law is a continuation of Erasmus Darwin's (1731-1802) observation that when one stops, after rotating for a period round the body axis, the apparent motion of the surrounding changes from horizontal to vertical when the head is inclined. Purkinje found that the direction of the apparent motion is determined by the position of the head during the rotation (Purkinje’s law of vertigo).
