A theory for self-sustained balanced states in absence of strong external currents
David Angulo-Garcia, Alessandro Torcini
Recurrent neural networks with balanced excitation and inhibition exhibit irregular asynchronous dynamics, which is fundamental for cortical computations. Classical balance mechani…
Is the cortical dynamics ergodic? A numerical study in partially symmetric networks of spiking neurons
Ferdinand Tixidre, Gianluigi Mongillo, Alessandro Torcini
Cortical activity in-vivo displays relaxational time scales much longer than the membrane time constant of the neurons or the deactivation time of ionotropic synaptic conductances.…
Synaptic shot-noise triggers fast and slow global oscillations in balanced neural networks
Denis S. Goldobin, Maria V. Ageeva, Matteo di Volo +2
Neural dynamics is determined by the transmission of discrete synaptic pulses (synaptic shot-noise) among neurons. However, the neural responses are usually obtained within the dif…
Emergence and maintenance of modularity in neural networks with Hebbian and anti-Hebbian inhibitory STDP
Raphaël Bergoin, Alessandro Torcini, Gustavo Deco +2
The modular and hierarchical organization of the brain is believed to support the coexistence of segregated (specialization) and integrated (binding) information processes. A relev…
