Three-neuron model of compensatory eye-movements in response to vestibular stimulation

Generation of compensatory eye-movements, which arise in response to vestibular stimulation, is described in the frame of three-neuron pathway, by which the vestibulo-ocular reflex is conducted. A mathematical model of the reflex based on literature is presented in the paper. All parameters and variables of the model proposed have clear physiological meaning. Incompleteness of the vestibulo-ocular interconnections described in the literature is shown. For the particular case of head rotation about the vertical axis an experiment is proposed and performed, the results of the experiment allow to identify unknown parameters of the model. Torsional vestibulo-ocular reflex readaptation process to usual earth gravity conditions after long-term orbital flight was experimentally investigated.
