• Here is an XPP file for computing first passage times for a simple scalar neuron model. The figure shows some histograms for (red I=0,sigma=0.2;green I=0,sigma=0.4; white I=-.1,sigma=.2)
• Here is an XPP file for computing the FI curve for a simple scalar neuron model. The plot shows the FI curve as sigma goes from 0 to 0.5.
• Here is a very complex XPP file to solve the first passage BVP using AUTO. The plot shows the results of this for sigma=1 and 0.1 Note AUTO has a bit of a problem when I is negative and large.
• The FI curve with noise can be approximated by the following function. Let F(I) be the deterministic curve and define

L(x,b) =x/(1-exp(-b*x))

As b gets large, L(x,b) approaches the curve max(x,0). So, 1/b is like the amount of noise and FI(I) = F(L(I,b)) is a decent fit. We will use something like this later when we create firing rate models.
