| summary | Optic flow is the pattern of motion that falls on our retinas when we move within our environment. It can be used by our visual system to monitor heading or walking speed. In this talk, I will present recent works from my team which clarified where and how optic flow is processed in the primate brain. I will first describe the results of neuroimaging experiments realized in both humans and macaques which determined the cortical networks processing optic flow in these two species and suggest that they are very similar. I will then show how computational approaches based on spiking neural networks and unsupervised learning can model how optic flow selectivity emerges from visual experience during development. Finally, I will present psychophysical results showing how optic flow is processed in patients suffering from macular degeneration. |
