“…Using a network of FitzHugh-Nagumo (FN) neurons [783,784], the frequency of the coherent oscillations was found to be highly modulated by the network topology [785]. In contrast with the HH model, the propagation speed in the FN network is not dependent of the wiring structure.…”

“…Possibilities include largely distributed changes in structural (Cohen-Cory et al, 2010) and functional connectivity (Thomason et al, 2009). As connectivity determines neural network synchronization and dynamics (Lago-Fernández et al, 2001;Kitano and Fukai, 2007), synchronization may constitute a relevant mechanism by which BDNF affects cognitive functions. Such possible mechanisms have until now not been investigated.…”

“…We find that even this simple model exhibits a rich repertoire of distinct dynamical behaviors as a function of the density p of added shortcuts: a low p regime characterized by persistent periodic activity that is bistable with the quiescent state, a transition to failure with increasing p, followed by a reemergence of long-lasting disordered activity. We note that a SWN with unidirectional shortcuts has been considered in a different regime by Lago-Fernández et al [14,15] to address the possibility of rapid synchronization among conductance-based neurons of the HodgkinHuxley type.The model considered here consists of a onedimensional array of N integrate-and-fire neurons (IFNs) in which a SWN topology is created through the addition of a density p of unidirectional long-range couplings. The membrane potential of the IFNs is determined by…”
