The ﬁrst passage time distribution for the slightly more general case of Brownian motion {Xt: t ≥ 0} with zero drift and diffusion coefﬁcient σ2 > 0, starting at the origin, may be obtained by applying the formula for the standard WebMay 31, 2015 · The first passage time density of a diffusion process to a time varying threshold is of primary interest in different fields. Here, we consider a Brownian motion in presence of an exponentially decaying threshold to model the neuronal spiking activity. haa account

"One of the simplest and omnipresent stochastic systems is that of the Brownian particle in one dimension. This system describes the motion of a particle which moves stochastically in one dimensional space, with equal probability of moving to the left or to the right.

The threshold can be a barrier, boundary or specified state of a system.
