Figure 5
Model output and firing rates of neurons located on the figural region and on the background region.
The light-dark squares in the centre column represent the NxN matrices of neurons of the model. The coloring of the matrices illustrates the membrane potential where light grey indicates high activity and dark grey zones low activity level. The white small circles depict neurons located on the figural and background regions. The arrows originating from them point to the corresponding spike responses of these neurons over time. Note that the activity pattern of the first layer of the model mirrors the texture input whereas the second layers only neurons at the figural region spike. Lower two BW squares represent the texture input, Dotted line demarcates the stimulus. Time is from stimulus onset.
