Adaptive behavior with stable synapses

1 code implementation10 Apr 2024 Cristiano Capone, Luca Falorsi, Maurizio Mattia

However, such rapid changes are not coherent with the timescales of synaptic plasticity, suggesting that the mechanism responsible for that could be a dynamical network reconfiguration.

Escape time in bistable neuronal populations driven by colored synaptic noise

no code implementations8 Apr 2024 Gianni Valerio Vinci, Maurizio Mattia

Local networks of neurons are nonlinear systems driven by synaptic currents elicited by its own spiking activity and the input received from other brain areas.

Self-consistent stochastic dynamics for finite-size networks of spiking neurons

no code implementations29 Dec 2021 Gianni V. Vinci, Roberto Benzi, Maurizio Mattia

Despite the huge number of neurons composing a brain network, ongoing activity of local cell assemblies composing cortical columns is intrinsically stochastic.

valid

A `Rosetta stone' for the population dynamics of spiking neuron networks

no code implementations5 Nov 2021 Gianni V. Vinci, Maurizio Mattia

Populations of spiking neuron models have densities of their microscopic variables (e. g., single-cell membrane potentials) whose evolution fully capture the collective dynamics of biological networks, even outside equilibrium.

Scaling of a large-scale simulation of synchronous slow-wave and asynchronous awake-like activity of a cortical model with long-range interconnections

no code implementations22 Feb 2019 Elena Pastorelli, Cristiano Capone, Francesco Simula, Maria V. Sanchez-Vives, Paolo del Giudice, Maurizio Mattia, Pier Stanislao Paolucci

Cortical synapse organization supports a range of dynamic states on multiple spatial and temporal scales, from synchronous slow wave activity (SWA), characteristic of deep sleep or anesthesia, to fluctuating, asynchronous activity during wakefulness (AW).

Slow Waves Analysis Pipeline for extracting the Features of the Bi-Modality from the Cerebral Cortex of Anesthetized Mice

1 code implementation22 Feb 2019 Giulia De Bonis, Miguel Dasilva, Antonio Pazienti, Maria V. Sanchez-Vives, Maurizio Mattia, Pier Stanislao Paolucci

Cortical slow oscillations are an emergent property of the cortical network, a hallmark of low complexity brain states like sleep, and represent a default activity pattern.
