abstract = {<p style="text-align: justify;">In this work, we consider the Fokker-Planck equation of the Nonlinear Noisy
Leaky Integrate-and-Fire (NNLIF) model for neuron networks. Due to the firing events
of neurons at the microscopic level, this Fokker-Planck equation contains dynamic
boundary conditions involving specific internal points. To efficiently solve this problem and explore the properties of the unknown, we construct a flexible numerical
scheme for the Fokker-Planck equation in the framework of spectral methods that can
accurately handle the dynamic boundary condition. This numerical scheme is stable
with suitable choices of test function spaces, and asymptotic preserving, and it is easily extendable to variant models with multiple time scales. We also present extensive
numerical examples to verify the scheme properties, including order of convergence
and time efficiency, and explore unique properties of the model, including blow-up
phenomena for the NNLIF model and learning and discriminative properties for the
NNLIF model with learning rules.</p>},
