is there a way to generate correlated Gaussian white noise in the NEST?
It is stated that the "noise_generator" can be used to inject a "Gaussian white” noise current into a node, also it is stated that all targets of a noise generator receive different currents. I am looking for a way to produce correlated white noise, or equally send the same noise to all targets of the "noise_generator".
In the next step, I like to have a small duration of noisy current, then inject the same current into different neurons at different times.

Dear Saeed,
You are right that the noise_generator generates a different noise for each target. The noise is generated as explained here: https://nest-simulator.readthedocs.io/en/stable/models/noise_generator.html To supply the same noise to all targets, you could generate the noise in python and pass this as the argument "amplitude_times" to a step_current_generator, see https://nest-simulator.readthedocs.io/en/latest/models/step_current_generato...
The step_current_generator will then send this noise to all of its targets. Creating the noise outside NEST and passing it to different step_current_generators connected to different neurons also lets you realize the next step that you mentioned if you also specify the argument "amplitude_times" .
Best,
David
