The Hydrodynamic Limit of Neural Networks with Balanced Excitation and Inhibition

James MacLaurin, Pedro Vilanova

The theory of `Balanced Neural Networks' is a very popular explanation for the high degree of variability and stochasticity in the brain's activity. We determine equations for the…

The Hydrodynamic Limit of Hawkes Processes on Adaptive Stochastic Networks

James MacLaurin

We determine the large size limit of a network of interacting Hawkes Processes on an adaptive network. The flipping of the node variables is taken to have an intensity given by the…

Large Deviations of Mean-Field Jump-Markov Processes on Structured Sparse Disordered Graphs

James MacLaurin

We prove a Large Deviation Principle for {\color{blue} jump-Markov } Processes on sparse large disordered network with disordered connectivity. The network is embedded in a geometr…

Neural Fields and Noise-Induced Patterns in Neurons on Large Disordered Networks

Daniele Avitabile, James MacLaurin

We study pattern formation in class of a large-dimensional neural networks posed on random graphs and subject to spatio-temporal stochastic forcing. Under generic conditions on cou…

Large Deviations of Piecewise-Deterministic-Markov-Processes with Application to Stochastic Calcium Waves

Gaetan Barbet, James MacLaurin, Moshe Silverstein

We prove a Large Deviation Principle for Piecewise Deterministic Markov Processes (PDMPs). This is an asymptotic estimate for the probability of a trajectory in the large size limi…

Population Level Activity in Large Random Neural Networks

James MacLaurin, Moshe Silverstein, Pedro Vilanova

We determine limiting equations for large asymmetric `spin glass' networks. The initial conditions are not assumed to be independent of the disordered connectivity: one of the main…
