poiss_gen – Generate spikes with Poisson process statistics

Description

The poisson_generator simulates a neuron that is firing with Poisson statistics, i.e. exponentially distributed interspike intervals. It will generate a unique spike train for each of it’s targets. If you do not want this behavior and need the same spike train for all targets, you have to use a parrot_neuron between the poisson generator and the targets.

Parameters

The following parameters can be set in the status dictionary.

rate	Hz	Mean firing rate
origin	ms	Reference time for start and stop
start	ms	Activation time, relative to origin
stop	ms	Deactivation time, relative to origin
