Hello! I need to stimulate n axons with IClamp. Unfortunately only the first axon I instantiate gets stimulated no matter what axon I choose in IClamp( <position>, <section>). In the following minimal working example, I create two axons. I connect IClamp to the second one but the first one gets stim...

:-) Thank you so much! It works now.

Thank you very much, Ted. I did not know enough about the properties of xtra . If I set the pointers like in the link you send, xtra does not produce an error anymore. Does not stimulate either, but that's something I'll look into later. The strange effect of extracellular remains. With and without ...

Hello, I am trying to use VecStim to input a spike train into an axon. I also need to record the membrane currents (via extracellular ) and want to additionally stimulate the axon externally (via xtra ). When inserting nothing but Hodgkin-Huxley ( hh ) channels into the membrane, everything is fine....
