FIG. 1.

Head movement localization responses to narrow band noises (NBN) in the azimuth and elevation directions. A Typical example of a head saccade to a long (1,000 ms) stimulus (500 Hz, 70 dB SPL at location Azi = −60°, Ele = 0°) from patient P2. Azimuth (black line) and elevation (gray line) are plotted as a function of time. The stimulus event (1,000 ms) is indicated by the bold black line. B Two-dimensional trajectory of the same head movement. C Example of a head saccade to a short (150 ms) stimulus (3 kHz, 55 dB SPL at location Azi = −33°, Ele = 0°) from patient P1. D Two-dimensional trajectory.
