A computational model of perceptual fill-in following retinal degeneration.

abstract：:Hilar mossy cells represent a unique population of local circuit neurons in the hippocampus and dentate gyrus. Here we use electrophysiological techniques in acute preparations of hippocampal slices to demonstrate that depolarization of a single hilar mossy cell can produce robust inhibition of local GABAergic afferen...

Because a cell's response properties are determined by the inputs it receives, receptive field dynamics are likely to involve changes in the relative efficacy of different inputs to the cell. To test this h...
