Fluctuation-driven plasticity allows for flexible rewiring of neuronal assemblies
Federico Devalle, Alex Roxin
Synaptic connections in neuronal circuits are modulated by pre- and post-synaptic spiking activity. Heuristic models of this process of synaptic plasticity can provide excellent fi…
Synchrony-induced modes of oscillation of a neural field model
Jose M. Esnaola-Acebes, Alex Roxin, Daniele Avitabile +1
We investigate the modes of oscillation of heterogeneous ring-networks of quadratic integrate-and-fire neurons with non-local, space-dependent coupling. Perturbations of the equili…
Firing rate equations require a spike synchrony mechanism to correctly describe fast oscillations in inhibitory networks
Federico Devalle, Alex Roxin, Ernest Montbrió
Recurrently coupled networks of inhibitory neurons robustly generate oscillations in the gamma band. Nonetheless, the corresponding Wilson-Cowan type firing rate equation for such…
Macroscopic description for networks of spiking neurons
Ernest Montbrió, Diego Pazó, Alex Roxin
A major goal of neuroscience, statistical physics and nonlinear dynamics is to understand how brain function arises from the collective dynamics of networks of spiking neurons. Thi…
How effective delays shape oscillatory dynamics in neuronal networks
Alex Roxin, Ernest Montbrio
Synaptic, dendritic and single-cell kinetics generate significant time delays that shape the dynamics of large networks of spiking neurons. Previous work has shown that such effect…
Many Attractors, Long Chaotic Transients, and Failure in Small-World Networks of Excitable Neurons
Hermann Riecke, Alex Roxin, Santiago Madruga +1
We study the dynamical states that emerge in a small-world network of recurrently coupled excitable neurons through both numerical and analytical methods. These dynamics depend in…
