Model on Visualization and Analysis for Peripheral Drift Illusion

Abstract

The peripheral drift illusion yields rotating motion on our peripheral vision. It has been reported that the order of four different luminance regions is essential for this illusion (black, blue (dark gray), yellow (light-gray), and white). Moreover, it has been suggested that luminance or contrast dependent latency of V1/MT direction selective cells contributes on induction of the rotating illusory motion. In the present work, we modeled V1 and MT as a retinotopic map of those direction selective cells and investigated whether the illusory rotating motions in peripheral drift illusion can be reproduced. In our simulation, the illusory rotating motions are represented in the transition of neuronal responses in both V1 and MT when the responses are visualized in contrast domain, but not in luminance domain, suggesting that the contrast is key information for induction of the rotating motion in the peripheral drift illusion.
