Interaction of vestibular-driven head and eye movements.

<p><i>A</i>, Average gaze, eye and head position (top panels) and velocity (bottom panels) traces during stimulations when the head was restrained and free. Gray bars indicate stimulus duration and shading represents standard error. <i>B</i>, Plots of average gaze movement amplitude during pulse trains delivered at 50, 100, 200 and 300pps when head-restrained versus free. <i>D</i>, Plots of average eye movement amplitude during pulse trains delivered at 50, 100, 200 and 300pps when head-restrained versus free.
