Fig. 12.6. Effect of relative input size on synchronization. A network of 90 neurons with both excitatory and inhibitory lateral connections was simulated for 500 iterations. The excitatory connection radius was 14 and inhibitory connections were global (as shown at right for neuron 45). The network was given two spatially separated inputs, and the size of the second input was varied. The rows (i.e. neurons) that received input are marked by black solid bars on the left. (a) The two inputs were the same size, activating neurons [19..36] and [55..72]. (b) One input was twice as long as the other input, activating neurons [16..45] vs. [61..75]. (c) One input was three times as long as the other input, activating neurons [1..45] vs. [61..75]. In all cases, the inputs are robustly bound and segmented, showing that the behavior is not affected by variation in the size of the input.
