Receptor Mechanisms at the Same Location on a Cell

[dabliss]

I have a point-process NMDA receptor mechanism (NMDASyn) that I'd like to place at the center of my single-compartment neuron. However, rather than have just one instance of NMDASyn, I'd like a new one for every connection my cell makes. Is it OK to have all these instances of NMDASyn placed at the same location in my cell? How should I expect their effects on V_m to be summed?

Thanks,
Dan

Yes.

Each one will generate its own current. NEURON knows how to deal with charge balance.
