Re: Ephaptic connections in network
Yes, ephaptic field effects. It is a CNS model of pyramidal cells. Axons are not really a part of it. I am modeling the effect of bursting cells on their neighbors--essentially the local currents produced by active cells, and how they might recruit nearby cells. These effects become more prominent w...

Ephaptic connections in network
I'm trying to add ephaptic connections to a ~100 neuron network. I'd like to have one group of them produce a net output, and have the other group "see" it. Unfortunately, the network is a parallel context version, and I'm not sure how to even start. I do not need very sophisticated device...

multithreading without the GUI
I have a working model, written to be MPI-ready, that was running on 6.1. What needs to be done to run this with multithreading capabilities in 7.0? I do not use the GUI, and run long batches, so it needs to be either commandline changes or something to write into the .hoc files (sorry, I haven't be...

since the first 1000 netcons are created with a ind = pnm.nc_append(preGID, postGID, synID, g, delay) call, how do I implement the new netcons within PNM structure, if there is no GID for the netcon source? It is not apparent to me how to combine your example with my pnm.nclist (or append to it with...

So I'm almost certain those art cell events were initialized via a netstim call (this is exactly what would happen if the original art_cell=NetStim() was set to delay 50, interval 10, number 10). So I'm guessing the answer to the first question is that I should have seen <NONE> of the random netcon ...

How does spikevec treat artificial cells?
I've a question about the operation of the pnm.gatherspikes(). I have a network with biophysical cells, for which the spikevec is working just fine. I recently added some artificial cells that also appear to be working correctly. These cells' only action is to produce random synaptic potentials on t...

Adding random synaptic events
I am trying to learn the syntax for adding synaptic events to a network. I have created the "toy network" .hoc file per the tutorial ( http://www.neuron.yale.edu/neuron/static/docs/netbuild/hybrid/outline.html ), with its list of two cells and a NetStim. This .hoc makes use of cell_append ...

Cannot save
I am running WinXP on my own computer (no other users/admin). I previously had installed version 6.0.3, and it was running fine. Then after a long delay I got back into gui work and tried saving .hoc and .ses files and got error messages stating the files could not be opened for writing, and was una...
