  text: Starting from a microscopic model for a system of neurons evolving in time
    which individually follow a stochastic integrate-and-fire type model, we study
    a mean-field limit of the system. Our model is described by a system of SDEs with
    discontinuous coefficients for the action potential of each neuron and takes into
    account the (random) spatial configuration of neurons allowing the interaction
    to depend on it. In the limit as the number of particles tends to infinity, we
    obtain a nonlinear Fokker-Planck type PDE in two variables, with derivatives only
    with respect to one variable and discontinuous coefficients. We also study strong
    well-posedness of the system of SDEs and prove the existence and uniqueness of
    a weak measure-valued solution to the PDE, obtained as the limit of the laws of
    the empirical measures for the system of particles.
