want_all_spikes recording from axon

Post by bll5z6 » Tue Jun 19, 2018 1:57 pm

Hi all,

I have a model that includes axo-axonic cells that cause pyramidal cells to fire APs in the axon that do not backpropagate to the soma. I want to use the ParallelNetManager's want_all_spikes() because it's easy but it seems to only record spikes at the soma. Is there a simple way to force it to record from a certain section (in my case the distal axon)? Thanks!

Ben

If your model has actually been parallelized, then as part of model setup a NetCon will have been attached to each presynaptic cell's spike trigger zone and assigned a gid (global identifier). Those gids are what want_all_spikes() uses to capture the spike times. If you want to detect spikes at one or more additional locations in a cell, you have to attach NetCons to each of those locations and assign gids to them too.
