Title: A Quasi-Stationary Approach to Metastability in a System of Spiking Neurons with Synaptic Plasticity
Abstract: After reviewing the behavioral studies of working memory, we argue that metastable states constitute candidates for the type of transient information storage required by working memory. We then present a simple stochastic model of neural network whose synapses exhibit short-term facilitation. The metastable properties of this system are studied quantitatively, through the analysis of its quasi-stationary distribution. We will present both analytical and computational results illustrating the usefulness of the theory of quasi-stationary distributions in the study of metastable dynamics.
