Computer Based Analysis and Synthesis of Retinal Function.

Abstract

The vertebrate retina sequentially transforms patterns of neural activity through 5 separate, serially arranged sheets of cells. These neuronal patterns become increasingly complex at each successive layer. Our objectives is to determine the parameters in space and time for the transfer functions that transform the patterns at successive layers. We have extracted the space and time constants for retinal processing from the physiological data taken from single cells at each retinal layer. These space-time parameters drive an image processing computer, the PIPE. The resulting program represents a tentative blueprint for design of a retina, and some of these values have been used by modelers to make artificial retinas, including the silicon retina developed by Misha Mahawold in Carver Mead's laboratory.
