Abstract
In Schindler et al. (2005) an approximation of the instantaneous firing rate is obtained within a non stationary Leaky Integrate-and-Fire (LIF) neuron model whose dynamics is described by a Langevin equation with an oscillating drift. The purpose of the present paper is to exploit a space-time transformation to be led to the standard LIF model. We are able to point out the ranges of validity of an exponential approximation to p.d.f. of the first-passage-time as frequency, stimulus amplitude and diffusion constant are made to vary.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
