Figure 1: Implementation of the greedy pursuit using Integrate-and-Fire Neurons. We show the raster plot of 16 neurons tuned for different orientations for the feed-forward (black bars) and the sparse spike coding (white bars) models during the first 150 ms. We simulated here the activity of a network of Integrate-and-Fire neurons tuned to form a simple model of an hyper-column in the primary visual area (V1) to the presentation of a horizontal edge at t=0. In thz sparse coding model, the correlation linked to the information already detected is propagated as a hyper-polarizing and shunting lateral interaction to the neighboring neurons: the response in both latency and spiking frequency to the oriented edge is clearly more selective.
