PyNEST Microcircuit: Simulation ParametersΒΆ

Run this example as a Jupyter notebook:

See our guide for more information and troubleshooting.

A dictionary with parameters defining the simulation.

    # list of recording devices, default is 'spike_recorder'. A 'voltmeter' can

    # may not run correctly if there is < 4 virtual processes

    "overwrite_files": True,

    # is run on a local machine.
