Abstract
We studied the effects of change of head position in the pitch plane on the ability to hold horizontal eccentric gaze in five patients with cerebellar disorders. All patient showed a change in the time constant of horizontal centripetal drift when the head was pitched forward or back. This result suggests that otolithic inputs can influence the neural integrator for horizontal eye movements and indicates the value of testing horizontal gaze holding in different head positions.
