We are trying to create an axon that synapses back onto the soma or onto a dendrite and are having problems figuring out how to do this. Any help would be greatly appreciated. Thanks.

Attach an ExpSyn or Exp2Syn to the section where the synapse is to be located, and drive it with a NetCon that monitors the appropriate location in the axon for spikes. Example:

Code: Select all

objref ampasyn, nc
dend ampasyn = new ExpSyn(0.5)
axon nc = new NetCon(&v(1), ampasyn)
nc.weight = 1e-3 // single event delivered to ampasyn will produce 0.001 uS peak conductance

These classes and their usage are documented in the Programmer's Reference--see http://www.neuron.yale.edu/neuron/stati ... rence.html
