Abstract(in English) | Tang et al. reported that there is a possibility of existence of the binocular rivalry in Drosophila. In this paper, under the hypothesis that the binocular rivalry in Drosophila is realized by a circuit of Lobula plate tangential cells (LPTCs) known as motion detectors, we explore the mechanism of the binocular rivalry by using a mathematical model of LPTCs circuit. Firstly, we constructed a simple circuit model in which electrically coupled cells were unified to a single cell, and all cells were described by the McCulloch-Pitts neuron model. We analytically confirmed that when giving both forward and backward translation stimuli, there are multiple stable states containing two states corresponding to responses to clockwise and counterclockwise rotation stimuli. Next we constructed a detailed model that consists of the conductance-based neuron model. We numerically confirmed that when giving forward translation stimuli, two firing cells, which separately exist in right and left hemispheres and have a preferred direction opposite to each other, were alternately excited/inhibited depending on noise fluctuations. There results suggest that dynamical activities of LPTCs circuit might involve in the binocular rivalry. |
