Neural Activity of Heterogeneous Inhibitory Spiking Networks with Delay
Stefano Luccioli, David Angulo Garcia, Alessandro Torcini
We study a network of spiking neurons with heterogeneous excitabilities connected via inhibitory delayed pulses. For globally coupled systems the increase of the inhibitory couplin…
Death and rebirth of neural activity in sparse inhibitory networks
David Angulo-Garcia, Stefano Luccioli, Simona Olmi +1
In this paper, we clarify the mechanisms underlying a general phenomenon present in pulse-coupled heterogeneous inhibitory networks: inhibition can induce not only suppression of t…
Clique of functional hubs orchestrates population bursts in developmentally regulated neural networks
Stefano Luccioli, Eshel Ben-Jacob, Ari Barzilai +2
It has recently been discovered that single neuron stimulation can impact network dynamics in immature and adult neuronal circuits. Here we report a novel mechanism which can expla…
Collective dynamics in sparse networks
Stefano Luccioli, Simona Olmi, Antonio Politi +1
The microscopic and macroscopic dynamics of random networks is investigated in the strong-dilution limit (i.e. for sparse networks). By simulating chaotic maps, Stuart-Landau oscil…
Discrete Breathers in a Realistic Coarse-Grained Model of Proteins
S. Luccioli, A. Imparato, S. Lepri +2
We report the results of molecular dynamics simulations of an off-lattice protein model featuring a physical force-field and amino-acid sequence. We show that localized modes of no…
Collective behavior of heterogeneous neural networks
Stefano Luccioli, Antonio Politi
We investigate a network of integrate-and-fire neurons characterized by a distribution of spiking frequencies. Upon increasing the coupling strength, the model exhibits a transitio…
