Thank you for the detailed response including the example. The situation I am facing is slightly different though. I am in the process of building (in fact, mostly porting from GENESIS) a detailed cell model I created earlier, which includes a total of about 15 different biophysical mechanisms in a ...

Dear All, Is there a way to define subsets in the Cell Builder in a parametric way (e.g., include all sections which are less than 300 micrometers away from the soma)? If not, is there a simple way to achieve this using the hoc interpreter, such that the subset definitions are used subsequently by t...

Thanks for the detailed response. While a fix for this is being developed (allow specification of the self-event that is to be moved?), the interim workaround is to limit each instance of the saturating synapse mechanism AMPA_S to a single input stream per instance--that is, one NetCon per AMPA_S in...

OK, you have discovered a bug in the mod file. Declaring the variables RANGE or GLOBAL is not the fix. Yes, I realize that these are two independent issues - still, I do not understand why the synapse model does not work at all (with any kind of input) when parameters such as synaptic time constant...

Thanks for the reply. By "defining an additional type of synapse in analogy to the two existing ones," I meant only that the synapse defined by the ampa.mod file had to be added to the cell template "StandardIF" in PyNN which already had two other (simpler, non-saturating) synaps...

I am trying to use the the saturating synapse model described in Chapter 10 of the NEURON Book in a network simulation. I compile the .mod file listed as ampa.mod in the book, and then attempt to drive a generic conductance-based linear integrate-and-fire neuron through synapses of this type. I actu...

Thank you for your help. Rebuilding mpich2 with shared library support was indeed the necessary first step, but then I also had to modify the setup.py script to get rid of an error caused in mpic++ by the remaining empty references to the missing iv libraries. In the end, I managed to make it work -...

Dear All, I am trying to install Neuron 7.1 with MPI and Python support, but without X11 on an Opteron blade server running Fedora 9, with the ultimate goal of using it with PyNN. I can compile Neuron with the Python interpreter (using the options --with-nrnpython=/usr/bin/python --with-paranrn --wi...
