Modulation of retrieval dynamics of episodic memory in heteroclinic networks. (A) Networks inside the circles represent the intrinsic architecture of interacting envelope patterns. Ω characterizes the frequency of the external forcing. (B) Complex structure of the heteroclinic synchronization: Period T corresponds to the cyclic winnerless competition switching between episodes X, Y, and Z and is depicted as a function of the forcing frequency Ω under a small Gaussian noise with zero correlation in Equation (1). The region in between synchronized regimes displays chaos (Rabinovich et al., 2006a).
