Modeling Visual Illusions Induced by Localized Stimuli Using Neural Fields

The paper aims to investigate the theoretical modeling of visual illusions observed in Billock and Tsou's experiments, where a localized funnel pattern stimulus induces an orthogonal tunnel pattern in the surrounding region of the visual field. The authors use an Amari-type neural field equation to model the cortical dynamics and explore the role of excitatory and inhibitory neuronal activities in reproducing these nonlinear visual phenomena.
