Fig 1.
A represents the high intensity stimulus (HI) holding 38 lines and B the low intensity stimulus (LI) holding 19 lines.
The black lines are 0.42cm wide and 3.25 cm long (visual angle 0.93 deg) standing at an angle of 45 degrees. The lines are centered on a fixation point, 0.32 cm in diameter. The visual scene was presented in roughly 50 degrees in the subjects’ field of vision.

The response in A) torsional and B) skewing velocities for high intensity (black) and low intensity (white) stimuli during the early (0-5s), middle (7.5–12.5s), and late (15-20s) time period. Values are presented as means with standard deviation.
