Persistence of hierarchical network organization and emergent topologies in models of functional connectivity
Ali Safari, Paolo Moretti, Ibai Diez +2
Functional networks provide a topological description of activity patterns in the brain, as they stem from the propagation of neural activity on the underlying anatomical or struct…
Stochastic Amplification of Fluctuations in Cortical Up-states
Jorge Hidalgo, Luis F. Seoane, Jesus M. Cortes +1
Cortical neurons are bistable; as a consequence their local field potentials can fluctuate between quiescent and active states, generating slow 0.5-2 Hz oscillations which are wide…
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…
