Spike-Driven Synaptic Plasticity: Theory, Simulation, VLSI Implementation
We present a model for spike-driven dynamics of a plastic synapse, suited for aVLSI implementation. The synaptic device behaves as a capacitor on short timescales and preserves the memory of two stable states (efficacies) on long timescales. The transitions (LTP/LTD) are stochastic because both the number and the distribution of neural spikes in any finite (stimulation) interval fluctuate, even...
متن کاملExact Subthreshold Integration with Continuous Spike Times in Discrete-Time Neural Network Simulations
Very large networks of spiking neurons can be simulated efficiently in parallel under the constraint that spike times are bound to an equidistant time grid. Within this scheme, the subthreshold dynamics of a wide class of integrate-and-fire-type neuron models can be integrated exactly from one grid point to the next. However, the loss in accuracy caused by restricting spike times to the grid ca...
متن کاملSpike-Driven Synaptic Dynamics Generating Working Memory States
The collective behavior of a network, modeling a cortical module of spiking neurons connected by plastic synapses is studied. A detailed spike-driven synaptic dynamics is simulated in a large network of spiking neurons, implementing the full double dynamics of neurons and synapses. The repeated presentation of a set of external stimuli is shown to structure the network to the point of sustainin...
متن کاملFormation of working memory in networks of spiking neurons and spike-driven synapses
We study the evolution of the collective behaviour of a recurrent network of integrate-and-fire neurons, connected by synapses whose efficacies are subjected to a spike-driven, Hebbian long-term potentiation and a homosynaptic depression, as well as a short-term, frequency dependent depression. Through a mean field analysis, and numerical simulations of the coupled neural and synaptic dynamics,...

Queuing theory in a very simple Definition is a branch of mathematics for analysis and management of waiting lines. It is developed in the first years of twentieth century when telephone waiting Lines were studied. Servers are not necessarily human beings but in queuing systems that human Agents are servers, it is possible to consider the queuing system as a dynamic system. This is because in ...
