Re: MATLAB code for Poisson spike generator

[Erik Larsen <elarsen@xxxxxxx>]

Dear Ana,

a Poisson spike generator with a fixed mean rate for a given interval is very easy - you just need to generate random spike times according to a uniform probability density distribution during your time interval (number of spikes = mean rate * interval duration). This of course doesn't take refractoriness into account. Perhaps a simple way to incorporate that is to look at each successive spike time that you generate and check whether it occurs within the refractory period of another spike, and if so, reject that new spike and generate a new one.

Dear List,

I'm looking for MATLAB code for a Poisson spike generator, given a mean
rate, a certain duration and a refractory period. Could anyone provide the
code to do this?
Thank you in advance for any help.
Best regards,

Ana
