Fig. 4: Effect of signal frequency.
From: The small world coefficient 4.8 ± 1 optimizes information processing in 2D neuronal networks
As with Δt, for constant values of SW the efficiency of the grid ηgrid varies for varying values of the frequency of the originating input f (a). The density plots of \({\eta }^{{{\mathrm{nodes}}}}\) (b), \({\eta }^{{{\mathrm{grid}}}}\) (c), \({\eta }^{{{\mathrm{peak}}}}\) (d) as a function of \({\rm{SW}}\) and \(f\) show the combined influence of topology and frequency on the performance of the grid (\(\triangle t=120\,{{\mathrm{ms}}}\)). The diagrams of \({\eta }^{{{\mathrm{grid}}}}\) against \({\rm{SW}}\) extracted from the density plot in c for the values of frequency \(f=133\), \(\,200\), \(267\,{{\mathrm{Hz}}}\), and \(\triangle t=120\,{{\mathrm{ms}}}\) (e).
