Synopsis Of Research:
The primate retina provides an ideal locus for an interdisciplinary approach to visual science. Retinal physiology can be related to retinal anatomy and the cell biology of retinal neurons, and, going in the other direction, it can be compared with human psychophysical data. We record from retinal elements and use these data as a basis for modeling retinal processing and we also are closely concerned with how retinal signals form a basis for our perceptual performance. For example, color vision becomes much poorer in the retinal periphery. A recent series of experiments showed that this degradation is not due to inadequacies of retinal processing; it must have its origin in cortical mechanisms. Other interests include mechanisms of adaptation, coding of natural scenes and information content of spike trains in relation to spatial and temporal tasks. In addition, evolution of color vision in new-world primates is studied. Primates are the only mammals with full trichromatic color vision, and this seems to have evolved at the beginning of primate evolution, close to when New- and Old-World primates separated. The two groups differ significantly in their color vision capabilities, and studying this difference may help us understand how and way trichromacy evolved in this group. Finally, retinal physiology in relation to clinical tests provides an important practical application for our research.
