SUMMARY AND CONCLUSIONS
I. The ability of the vestibuloocular reflex (VOR) to undergo
adaptive modification after selective changes in the peripheral ves-
tibular system was investigated in rhesus monkeys by recording
three-dimensional eye movements before and after inactivation of
selective semicircular canals. In the preceding paper we showed
that the horizontal VOR gain evoked by passive yaw oscillations
after lateral semicircular canal inactivation recovers gradually over
time in a frequency-specific manner. Here we present the spatial
tuning of the adapted slow-phase eye velocity and describe its
spatiotemporal properties as a function of time after canal inactiva-
tion.
