Robustness of functional networks at criticality against structural defects
Abdorreza Goodarzinick, Mohammad D. Niry, Alireza Valizadeh +1
The robustness of dynamical properties of neuronal networks against structural damages is a central problem in computational and experimental neuroscience. Research has shown that…
Coexistence of scale invariant and rhythmic behavior in self-organized criticality
S. Amin Moosavi, Afshin Montakhab, Alireza Valizadeh
Scale-free behavior as well as oscillations are frequently observed in the activity of many natural systems. One important example is the cortical tissues of mammalian brain where…
Refractory period in network models of excitable nodes: self-sustaining stable dynamics, extended scaling region and oscillatory behavior
S. Amin Moosavi, Afshin Montakhab, Alireza Valizadeh
Networks of excitable nodes have recently attracted much attention particularly in regards to neuronal dynamics, where criticality has been argued to be a fundamental property. Ref…
Synchronization of oscillators through time-shifted common inputs
Ehsan Bolhasani, Yousef Azizi, Alireza Valizadeh +1
Shared upstream dynamical processes are frequently the source of common inputs in various physical and biological systems. However, due to finite signal transmission speeds and dif…
Stabilizing synchrony by inhomogeneity
Ehsan Bolhasani, Alireza Valizadeh
We show that for two identical neuronal oscillators with strictly positive phase resetting curve, isochronous synchrony is an unstable attractor and arbitrarily weak noise can dest…
Direct coupling and inhomogeneity assist neurons to detect correlation in low amplitude noises
E. Bolhasani, Y. Azizi, A. Valizadeh
We address a question on the effect of common stochastic inputs on the correlation of the spikes trains of two neurons when they are possibly nonidentical and are coupled through d…
