QUESTION
I'm trying to implement the spiking neuron of the Izhikevich model. The formula for this type of neuron is really simple:
v[n+1] = 0.04*v[n]^2 + 5*v[n] + 140 - u[n] + I
u[n+1] = a*(b*v[n] - u[n])
where v is the membrane potential and u is a recovery variable.
If v gets above 30, it is reset to c and u is reset to u + d.
Given such a simple equation I wouldn't expect any problems. But while the graph should look like , all I'm getting is this:
I'm completely at loss what I'm doing wrong exactly because there's so little to do wrong. I've looked for other implementations but the code I'm looking for is always hidden in a dll somewhere. However I'm pretty sure I'm doing exactly what the Matlab code of the author (2) is doing. Here is my full R code:
