Characterizing the effect of noise level and connectivity structure on the dynamics of excitatory network.

<p>(A) Fraction of time network adopts synchronous dynamics as a function of rewiring parameter for noise driven identical (I^e_ext = 1.05 for all neurons f_N = 0.00005, blue line), non-identical (I^e_ext = 0.95–1.15, f_N = 0.00005, green line) and deterministic dynamics for network of non-identical cells (I^e_ext = 0.95–1.15, red line). (B) The effect of the increasing noise level on the dynamics for the excitatory-only network with P_e = 0.15 for noise driven identical (I^e_ext = 1.05 for all neurons, blue line) and non-identical (I^e_ext = 0.95–1.15, green line).
