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

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