Fokker-Planck description of conductance-based integrate-and-fire neuronal networks

Steady dynamics of coupled conductance-based integrate-and-fire neuronal networks in the limit of small fluctuations is studied via the equilibrium states of a Fokker-Planck equation. An asymptotic approximation for the membrane-potential probability density function is derived and the corresponding gain curves are found. Validity conditions are discussed for the Fokker-Planck description and verified via direct numerical simulations.Physics, Fluids & PlasmasPhysics, MathematicalSCI(E)EI7ARTICLE2null8
