Binocular rivalry model based on hodgkin-huxley neuron

Abstract

Background: When two eyes are faced with two completely different sights, corresponding areas of the two eyes retina triggered with entirely two different stimulus and instead of receiving a fixed and stable image of two stimulus, brain perceive the alternation of the two images. This phenomenon is known as an intelligent tool to study cognitive processes. Methods: Taking a network of excitatory and inhibitory Hodgkin-Huxley type neuron in network architecture of visual cortex, the behavior of coupled spiking neuron in cortical brain that have a direct effect on the emergence of this phenomenon was modeled. To evaluate the performance of this model, direction lines as the two stimuli were applied to the eyes. Findings: Rebuilding the predominance time of each eye, and independence between the two successive dominance times were reported by this model. In addition, the effect of changes in the stimulus applied to each of the two eyes was studied and it was figured out that applied changing stimulus strength to one eye was affected only on dominance time of the other eye. Besides, increasing stimulus strength of both eyes decreased mean dominance time. Conclusion: Obtained results of this model were consistent with known experimental result for this phenomenon and many of dynamics features of this phenomenon reconstructed. Discussed theories in this field were also confirmed. � 2016, Isfahan University of Medical Sciences(IUMS). All rights reserved.
