Noise-enhanced neuronal reliability.
This work shows that noise can enhance the discharge time reliability in Hodgkin-Huxley neuron models stimulated by weak periodic and aperiodic inputs. By expanding the Fokker-Planck equation of an elementary model for excitable systems, the dependence of the optimal noise intensity on input characteristics is discussed.
