Figure 7

Mean gain (top) and phase lead (bottom) of eye versus the ideal response (−1 × head velocity) for the horizontal component of 3D angular AVOR for 5 normal chinchillas during 50°/s peak horizontal passive head rotation in darkness (circles) and for 3 bilaterally gentamicin-treated chinchillas during prosthetic stimulation encoding 50°/s horizontal passive head rotations (triangles). Error bars denote ±1SD. Only 1 animal yielded data for electrical stimulation at 15 Hz. The prosthetic stimulation responses have a shallower slope of gain versus frequency (nearly 0.5 on a log-log plot) and an upward shift in phase lead compared to normal. Gains for bilaterally-gentamicin-treated animals without prosthetic stimulation were below the physiologic and measurement noise of the recording system.
