Trial Task
0 A) Initial reading
1 B) 10 deg head saccades to the right – calibration of head sensor
2 C) Control task – no head or eye movements
3 D) Head center, Eye saccades to ± 10 deg
4 E) Head left 50 deg, Eye saccades to ± 10 deg
5 F) Head right 50 deg, Eye saccades to ± 10 deg
6 G) Gaze stabilization during sinusoidal head movement at 0.25 Hz (VOR)
7 H) Gaze saccades to ± 40 and ± 50 deg from midline
8 I) Smooth pursuit to left between 10 – 60 deg, followed by smooth pursuit to right between 10 – 60 deg
