Ratio of peak eye velocity with lateral connections to the peak eye velocity without lateral connections, for different lateral inhibition parameters (inhibitory width, ${\mathit{\sigma }}_{\mathrm{inh}}$, and inhibitory strength, $w_{\mathrm{inh}}$) and fixed excitatory lateral connections: $w_{\mathrm{exc}}=160$ pS, and ${\mathit{\sigma }}_{\mathrm{exc}}=0.4$ mm. All peak eye velocities are computed for a 21${}^{\circ }$ saccade amplitude (see Methods 2.9). Four parameter sets are marked by different symbols (see Fig. 14). Note that we used the parameter set $\circ$ throughout the paper to demonstrate the network activities. This parameter set was given by the genetic algorithm
