Single cells isolated in the vestibular complex of the awake monkey were studied as a function of stimulus input. The stimulus utilized in this study was sinusoidal tilt in the anterior-posterior plane about a vertical axis. Once a single cell was isolated its response to tilt was determined. Changes in amplitude and period of the stimulus brought about corresponding changes in the unitary discharge pattern which could best be described as spike frequency modulation of stimulus input. Some cells displayed a greater rate of change than others. Techniques and procedures necessary to record from the awake monkey are described.
