Dear Nosratullah, there’s no built-in mechanism for this in NEST. You have to manually post-process the data using a dict comprehension along these lines<https://stackoverflow.com/questions/44245293/filter-a-dictionary-o…on>: neuron_id = 123 spike_data = GetStatus(your_spike_detector, "events")[0] d = {k: [x for i, x in enumerate(v) if spike_data['senders'][i] == neuron_id] for k, v in spike_data.items()} If you know the neuron’s ID in advance, it might of course be easier to simply use another spike detector to just record the data from that one neuron.
