Phase-Coherence Transitions and Communication in the Gamma Range between Delay-Coupled Neuronal Populations
Figure 4
Phase coherence of two coupled bidirectionally neural populations for three different values of the inter-areal axonal delays .
Phase coherence spectrum and corresponding representative time series for (A,B),
(C,D), and
(E,F). The inter-areal delays follow a gamma distribution with a mean equal to corresponding inter-areal axonal delay
. The gray bars on the x-axes of plots A, C, and E delimit the gamma peak band (
). The phase coherence measure is averaged over
trials.
