Hi!
I've finally successfully recreated the Izhikevich
tutorial, but when I try to run the "homework" (i.e., generate the other results
in the paper), I find some strange results. Basically, every time I run the neuron with
Simulate(), the new simulation is ACCUMULATED after the previous result. I guess I should
reset the voltmeter between simulations somehow, but I couldn't find the adequate
commend... Can you give me any hint?
You can reset the data collected in the |voltmeter| by setting its
|n_events| field to 0 like so:
|vm = nest.Create("voltmeter") # create and connect neurons, simulate
vm.n_events = 0 # data from previous runs is gone |
For more information about the recording backend |memory|, see here:
https://nest-simulator.readthedocs.io/en/v3.4/models/recording_backend_memo…
More general information about recording from your simulations is here:
https://nest-simulator.readthedocs.io/en/v3.4/devices/record_from_simulatio…
Second, I am doing the homework for this tutorial,
reproducing the original results. Should it suffice to enter the right values for a, b, c,
and d? The results I am getting do not look too similar to the ones in the paper,
especially the bursts for the IB and CH neurons... any idea?
I am afraid, I’m not deep enough in the tutorial and can’t help you with
this one. One of my colleagues will have to pick this one up.
Cheers,
Jochen!
cheers
