Connecting cells using pnm.nc_append function

Post by Krishna Chaitanya »


I have two cell types which are point processes. Each of the cell type has certain neurons in the network and the connection I am trying to establish through pnm.nc_append. The spike events from cell type A are not being communicated to cell type B. But when I replace with NetCon statements, events are being delivered. I followed your paper "Translating Network Models ..." and also Migliore 2006 parallel implementation.

Can you kindly cite few examples where two point processes communicate with each other through pnm.nc_append function.

Thank you.

Free text search in ModelDB should turn up some examples. ParallelNetManager isn't much used; that doesn't mean it's deprecated, but it hasn't turned out to be all that helpful. We didn't use it for this tutorial article
Hines, M.L. and Carnevale, N.T.
Translating network models to parallel hardware in NEURON.
J. Neurosci. Methods 169:425-455, 2008
and we don't spend any time on it in the NEURON courses that we present. You might notice that the authors of
Migliore et al. Journal of Computational Neuroscience 21:119-129, 2006
haven't used it much lately.

Which is not to turn you away from using it yourself, but "just saying . . . " (as ramcdougal would say).
