Abstract
Up to very recently, the spatial arrangement of the photoreceptors of the human foveal center and their relationship to vision remained uncharted territory. With adaptive optics photo stimulation techniques that overcome the optical blur of the human eye and at the same time allows precise tracking of each photoreceptor cell as it is actively moved across the image formed on the retina, we can see what the photoreceptors see, and psychophysically study structure-function relationships on foveolar cell level. In this talk I will present recent anatomical and psychophysical results that will show both the similarities and differences in foveal mosaics in humans, and how the highly dynamic and adaptive sampling behavior of an eye aids visual performance.
