Nonlinear Dynamics of Binocular Rivalry & Migraine Auras

Abstract

Binocular rivalry is a fascinating phenomenon in which presentation of incompatible images to the two eyes results in a perceptual oscillations between the two monocular views. After demonstrating the phenomenon to the audience, the nonlinear dynamics underlying rivalry, rivalry memory, and traveling waves in rivalry will be discussed. Analogous traveling waves also arise during migraine auras, and the dynamics underlying these will also be developed using a simplified two-dimensional cortical model incorporating diffusion.
