Hi Adrien,

Many NEST generators provide independent spike trains to all of their targets, e.g. the poisson_generator and the sinusoidal_{poisson,gamma}_generators. For the latter, you can configure if all target should get independent spike trains or the same spike train.

If the firing rate of the generator is not too high compared to the time step, different neurons will receive input spikes at different time steps.

Is this what you need or are you thinking of something else?

Best regards,

Hans Ekkehard

Subject: [NEST Users] How to repeatedly stimulate random neurons in a population ?

[Some people who received this message don't often get email from adrien.dhollande@etu.u-paris.fr. Learn why this is important at https://aka.ms/LearnAboutSenderIdentification ]

Hi,

I am in trouble here: I would like to stimulate every delta_t a random subset of neurons in a population.
Should I create, for a population of size N, N generators and independently connect them to the N neurons, each spike generator provided with a random spike time series.
Or is there a clever way to do it ?

Thanks for any help!

Best,
Adrien
