A CHIMERA MODEL FOR MOTION ANTICIPATION IN THE RETINA AND THE PRIMARY VISUAL CORTEX

Résumé

We study motion anticipation in a mean field model of the primary visual cortex (V1) with a realistic retinal input. We assess the ability of this integrated retino-cortical model to reproduce experimental results on voltage dye optical imaging (VSDI) signal, in terms of two main quantities used to quantify anticipation: the latency and the time to peak. We unravel the effect of the stimulus features such as speed and contrast on anticipation. In addition, we explore the changes in the cortical wave of activation when V1 is driven by a retina output implementing different potential retina-driven anticipatory mechanisms, including gain control and lateral inhibition by amacrine cells.
