Figure 1

Long-term synchronization of two coupled entorhinal cortex stellate cell neurons with slightly different intrinsic firing frequencies. The mean of their intrinsic frequencies is plotted against a parameter (“Delta Coll 1”) relating the time series of peaks to the eigenvalues of the adjacency matrix, with 1 indicating completely in-phase synchronization and 0 completely out-of-phase. The color bar gives the difference in each intrinsic frequency from the mean (i.e., one-half their difference from each other).
