Mathematical Model of the Vestibuloocular Reflex.

Abstract

A mathematical model of the vestibuloocular reflex based on experimental data obtained from an alert cat was constructed and tested. This model includes quick-phases and also deals with the stochastic behavior of quick-phase timing and amplitude. The structure of the model is consistent with recent findings of neurophysiology. The slow-phase portion of the reflex is generated by integrating the output signal from the semi-circular canals. A common neural integrator is used for both quick-phase and slow-phase velocity signals. The quick-phase portion of the reflex is generated by a neural pulse generator which utilizes a closed-loop bang-bang type of control system (instead of an open-loop pulse generator operated by a sampler). This quick-phase model is based on the theory that rapid eye movements are caused by a mechanism which drives the eye to a commanded position in the orbit instead of using ballistic pre-programming.
