Discrete synaptic events induce global oscillations in balanced neural networks
Denis S. Goldobin, Matteo di Volo, Alessandro Torcini
Neural dynamics is triggered by discrete synaptic inputs of finite amplitude. However, the neural response is usually obtained within the diffusion approximation (DA) representing…
A new generation of reduction methods for networks of neurons with complex dynamic phenotypes
Inês C. Guerreiro, Matteo di Volo, Boris Gutkin
Collective dynamics of spiking networks of neurons has been of central interest to both computation neuroscience and network science. Over the past years a new generation of neural…
Coherent oscillations in balanced neural networks driven by endogenous fluctuations
Matteo Di Volo, Marco Segneri, Denis Goldobin +2
We present a detailed analysis of the dynamical regimes observed in a balanced network of identical Quadratic Integrate-and-Fire (QIF) neurons with a sparse connectivity for homoge…
Asynchronous and coherent dynamics in balanced excitatory-inhibitory spiking networks
Hongjie Bi, Matteo Di Volo, Alessandro Torcini
Dynamic excitatory-inhibitory (E-I) balance is a paradigmatic mechanism invoked to explain the irregular low firing activity observed in the cortex. However, we will show that the…
Optimal responsiveness and collective oscillations emerging from the heterogeneity of inhibitory neurons
Matteo di Volo, Alain Destexhe
The brain is characterized by a strong heterogeneity of inhibitory neurons. We report that spiking neural networks display a resonance to the heterogeneity of inhibitory neurons, w…
Coexistence of fast and slow gamma oscillations in one population of inhibitory spiking neurons
Hongjie Bi, Marco Segneri, Matteo di Volo +1
Oscillations are a hallmark of neural population activity in various brain regions with a spectrum covering a wide range of frequencies. Within this spectrum gamma oscillations hav…
