Emergence of synchronised and amplified oscillations in neuromorphic networks with long-range interactions
Ilenia Apicella, Daniel Maria Busiello, Silvia Scarpetta +1
Neuromorphic networks can be described in terms of coarse-grained variables, where emergent sustained behaviours spontaneously arise if stochasticity is properly taken in account.…
Hysteresis, neural avalanches and critical behaviour near a first-order transition of a spiking neural network
S. Scarpetta, I. Apicella, L. Minati +1
Many experimental results, both in-vivo and in-vitro, support the idea that the brain cortex operates near a critical point, and at the same time works as a reservoir of precise sp…
Neural Avalanches at the Critical Point between Replay and Non-Replay of Spatiotemporal Patterns
Silvia Scarpetta, Antonio de Candia
We model spontaneous cortical activity with a network of coupled spiking units, in which multiple spatio-temporal patterns are stored as dynamical attractors. We introduce an order…
Attractor networks and memory replay of phase coded spike patterns
Ferdinando Giacco, Silvia Scarpetta
We analyse the storage and retrieval capacity in a recurrent neural network of spiking integrate and fire neurons. In the model we distinguish between a learning mode, during which…
Associative memory of phase-coded spatiotemporal patterns in leaky Integrate and Fire networks
Silvia Scarpetta, Ferdinando Giacco
We study the collective dynamics of a Leaky Integrate and Fire network in which precise relative phase relationship of spikes among neurons are stored, as attractors of the dynamic…
A learning rule for place fields in a cortical model: theta phase precession as a network effect
Silvia Scarpetta, Maria Marinaro
We show that a model of the hippocampus introduced recently by Scarpetta, Zhaoping & Hertz ([2002] Neural Computation 14(10):2371-96), explains the theta phase precession phenomena…
