Figure 2.

Data and results of experiment A. (A) Exemplary traces of one subject (male, 26.1 years); the eye motion is shown as a thick red line and the head angle in the pitch plane as a thin blue line. The theoretically necessary eye movement to fully compensate for the platform movement is shown as a thin black line. Note that the platform motion is shown inverted, scaled to overlap with eye position when the movement is compensatory. (B) Time delays (upper part) and gain (lower part) of evoked eye movements of all subjects (mean ± SEM; N = 20) in experiment A with respect to stimulus cycle.
