Neural computations in the retina

Markus Meister, Jeff C. Tarr Professor of Molecular and Cellular Biology, Harvard University



Starting with the raw optical image projected on the photoreceptors, the retina performs a great deal of visual processing to compute about twenty parallel neural images, which are transmitted to the brain by the optic nerve fibers. I will describe some of these neural computations identified only recently and explain how they are accomplished by circuits of retinal interneurons. I will also discuss the implications of these newly discovered functions for processing in higher stations of the visual system that draw their inputs from the retina.
