seminar: Fast visual motion and cortical dynamics
speaker: Jean Lorenceau (LENA CNRS)abstract: Recent studies of the functional architecture of primary visual cortex reveal the existence of an intricate network of anisotropic long-range horizontal connections whose slow dynamics has the potential to influence perceptual visual processing, hence providing insights into its organisation and function. The presentation will focus on recent results in experimental psychology and human electrophysiology showing that perceptual biases in the perceived speed of visual motion sequences occur under particular conditions. These phenomena presumably result from the propagation of slow waves of activity through long-range horizontal connections in primary visual cortex, a view supported by computational modelling. The perceptual consequences of this functional architecture on perceptual binding of form and motion will be addressed and discussed.
