Functional Optimization in Complex Excitable Networks
Samuel Johnson, J. Marro, Joaquin J. Torres
We study the effect of varying wiring in excitable random networks in which connection weights change with activity to mold local resistance or facilitation due to fatigue. Dynamic…
Instabilities in Attractor Networks with Fast Synaptic Fluctuations and Partial Updating of the Neurons Activity
J. J. Torres, J. Marro, J. M. Cortes +1
We present and study a probabilistic neural automaton in which the fraction of simultaneously-updated neurons is a parameter, rho (0, 1) . For small rho, there is relaxation toward…
Complex Networks: Time-Dependent Connections and Silent Nodes
J. Marro, J. J. Torres, J. M. Cortes
We studied, both analytically and numerically, complex excitable networks, in which connections are time dependent and some of the nodes remain silent at each time step. More speci…
Sensitivity, Itinerancy and Chaos in Partly-Synchronized Weighted Networks
J. Marro, J. J. Torres, J. M. Cortes +1
We present exact results, as well as some illustrative Monte Carlo simulations, concerning a stochastic network with weighted connections in which the fraction of nodes that are dy…
Understanding Scale Invariance in a Minimal Model of Complex Relaxation Phenomena
P. I. Hurtado, J. Marro, P. L. Garrido
We report on the computer study of a lattice system that relaxes from a metastable state. Under appropriate nonequilibrium randomness, relaxation occurs by avalanches, i.e., the mo…
