Figure 7.

Recordings of torsional eye movements during static head tilt to the left (top) and to the right (bottom). Different colors show different repetitions of binocular recordings. Subjects fixate a small spot using a bite bar to stabilize the position of the head. After 60 s with the head straight up, the head is tilted 30° using a motor that rotates the bite bar. After another 60 s, the head is rotated back to the original position. Data recorded during blinks have been removed for clarity.
