Thresholds to trigger spikes of single excitable FHN neurons ( , ) as a function of signal periods.
(Left) time series of the mean field of the random network, (top), 0.1 (middle), 0.4 (bottom). (Right) corresponding histogram of ISI. Other parameters are , , , , , , .
(a) of random (circle), small-world (square), scale-free (diamond), and regular (triangle) network as a function of . (b) for these networks. These curves are plotted after interpolation. Markers are the same as in (a). Parameters are the same as in Fig. 2 .
as a function of for networks with different length limit. Solid lines are , dashed lines are . From bottom to top, the length limits are 7, 9, 11, and 20, respectively. Other parameters are the same as in Fig. 2 .
Effective diameter of random networks as a function of network size. Other parameters are the same as in Fig. 2 .
as a function of for different network sizes of random networks. From top to bottom, , 101, and 41. Other parameters are the same as in Fig. 2 .
curves of random networks to illustrate the effect of very large network size in the alternative way of choosing a smaller noise intensity, because the effect of large network size is similar to that of a smaller noise intensity. , (dot); , (star). Other parameters are the same as in Fig. 2 .
