See spikes in the Brain Visualizer (many neurons)

#1

Hi,

I’m trying to use the brain visualizer with a quite big version of my network (250’000 neurons for 2’150’000 synaptic connections). That works (display all layers with every neurons), but when I try to display the spikes by moving the “spike contrast” cursor, I don’t see spike happening, even though I record loads of spikes in the generic image viewer.

Am I doing something wrong to display the spikes? Should I state in some TF that I want to record the spikes?

Thanks for the help!
Best,
Alban

Hey Alban

For now, the spikes displayed in the brain visualizer are the same as the one displayed in the spiketrain, so you need to have a monitor TF:

import hbp_nrp_cle.tf_framework as nrp
@nrp.NeuronMonitor(nrp.brain.sensors, nrp.spike_recorder)
def all_neurons_spike_monitor(t):
    return True

Woaw that works! THank you very much :smiley:
