Section Visual Function / Electrophysiology

We are al dedicated interdisciplinary group of physicists, physicians and biologists. We try to understand ophthalmological diseases in the retina (especially dystrophies) and along the visual pathway, we develop testing methodology and look at basic visual function including lightness, contrast, motion, texture segregation and visual acuity.
