[The imitation of the effects of otolith-ocular asymmetry by eccentric rotation].
Today, investigation of the vestibuloocular reactions is the mainstream method of studying the vestibular asymmetry. Analysis of experimental data requires a model of otolith-ocular interaction. The proposed model is based on the literary data concerning measurements of ocular counter-rotation (OCR) and luminous line rotation (LLR) in experiments with eccentric rotation. The method utilizes a number of simplifications and suppositions, the basic of which are linearity of all phases of transformation of mechanic stimulus with the exception of the afferents' transmission function (proportionality of the nervous response to acceleration; the otolith-ocular response is proportional to the nervous response). It was demonstrated that the model qualitatively imitates the behavior of OCR and LLR in response to axifugal acceleration of the utricular otoliths and permits analysis of the role of various parameters of the otolith-ocular interaction. Comparison of calculated and experimental dependence of OCR and LLR on acceleration can help understanding of the otolith asymmetry.
