Figure 6. Changes in network topology and membrane conductance underlie the overall effect of gap junction connectivity on the network stability.

Figure 6

A Color panel is the surface plot of firing rate (averaged over non-overlapping bins of 100 ms and over all model neurons) vs. the probability Inline graphic to increase the leak conductance by Inline graphic in each one of the model neurons from the affected area (Inline graphic,Inline graphic) that did not previously share gap junction connection. Color code is blue for low firing rate and red for high firing rate. Horizontal axis is simulation time ([0–10] seconds). Background noise intensity Inline graphic for the set of Inline graphic model neurons was perturbed at Inline graphic (dashed red line through Panels B,C), and progressively increased to achieve 5-fold higher values at time 10 seconds (scale bar in lowest panel). Membrane leak conductance for Inline graphic model neurons was increased (as specified by Inline graphic) at time Inline graphic (dashed blue line through Panels B,C). B Raster plot of network's activity for Inline graphic. Other parameters: Inline graphic. C Third panel: Raster plot of network's activity for Inline graphic. Other parameters: Inline graphic.
