The objective of this paper is to present and analyze numerical approximation for the size structured neuron model. We propose finite volume approximations based on upwind and Lax–Wendroff for the partial differential equation originating in size structured neuron model (Perthame and Ryzhik in J Differ Equ 210:155–177, 2005) which is a conservation laws with source term. The developed numerical methods are analyzed for consistency, stability, and convergence. We perform some numerical experiments to verify the predicted theory of the numerical approximations constructed in this paper.
