Evaluating Rank-order Code Performance Using A Biologically Derived Retinal Model

B.S. Bhattacharya and S.B. Furber


We propose a model of the primate retinal gan- glion cell layout corresponding to the foveal-pit to test rank- order codes as a means of sensory information transmission in primate vision. We use the model for encoding images in rank-order. We observe that the model is functional only when the lateral inhibition technique is used to remove redundancy from the sampled data. Further, more than 80% of the input information can be decoded by the time only up to 10% of the ganglion cells of our model have fired their first spikes.
