Mechanisms of Zero-Lag Synchronization in Cortical Motifs
Figure 3
Synchronization dynamics and incoherence in Hodgkin-Huxley neurons.
(a) Incoherence in motif M3 does not depend on time delay. Colors indicate the different nodes. (b–d) Top panels show incoherence for M6, where colors represent different nodes, and bottom panels show crosscorrelations for M6 (blue) and M3 (black). Continuous lines indicate the cross-correlation coefficients at zero time lag, and dashed lines indicate the maximum cross-correlation coefficients for all time lags. Panels b, c and d represent pairs of nodes: 1–2, 1–3, and 2–3 respectively. Phase, anti-phase synchrony, and asynchrony can be found in motif M6 depending on the time delay (see exemplar time traces in supplementary Fig. S2). Results are averaged over 40 trials.
