Figure 5

Dynamics of the envelope fluctuations (black) and their associated LFPs (blue) for the same four parameter values used in Fig. 4: (a) R = 0.6288, (b) R = 1.2999, (c) R = 1.6900, and (d) R = 2.9194. Insets show the corresponding probability densities for these fluctuations, computed both numerically as well as analytically using Eq. 42 (red curve). Note how the size of the fluctuations and their durations increase as R increases, i.e. as the network becomes more synchronized.
