Abstract
Mahowald describes a silicon model of the computation performed by the first layer of visual processing, located in the outer plexiform layer of the retina [Mahowald 88,89]. The lateral spread of information at the outer plexiform layer is mediated by a two-dimensional resistive network. The voltage at every point in the network represents a spatially weighted average of the photoreceptor inputs. The farther away an input is from a point in the network, the less weight it is given. The weighting function decreases in a generally exponential manner with distance.
