PhD thesis :

Interactions between central and peripheral vision : behavioral and neurofunctional aspects in normal and pathological vision.

PhD supervision : Carole Peyrin

Funding : Grant AGIR-POLE-CBS (Université Grenoble Alpes)

I am interested in the properties of peripheral vision, and in the visual and neural mechanisms involved in the processing and integration of information from central and peripheral vision into a coherent whole. With this PhD project, we aim to investigate these questions in normal vision (healthy young and older people) and pathological vision (ophtalmic patients). The project takes advantage of pathologies that selectively impair central (age-related macular degeneration) or peripheral vision (glaucoma) for a better understanding of their respective contribution and their interaction during object and scene perception. In turn, the project investigates perceptual and cognitive visual impairments and residual abilities in healthy visual aging and patients with central or peripheral vision loss (age-related macular degeneration or glaucoma).
