EXPERIMENTAL DETERMINATION OF HUMAN VESTIBULAR SYSTEM RESPONSE THROUGH MEASUREMENT OF EYEBALL COUNTERROLL.
Abstract
An indirect measurement of the human vestibular system response was obtained through the measurement of eyeball counterroll. Human subjects were rotated about an axis through their line of sight at angular velocities varying from 0-30 rpm. The right eye was photographed and the angle of eyeball counterroll was determined by an optical correlation process. A mathematical model was formulated using Fourier curve fitting techniques. This model indicated that subjects with normal vestibular function demonstrate an eyeball counterroll which is a function of angular velocity and position with respect to the vertical. Subjects with known vestibular defects demonstrated a small counterroll. (Author)
