Thanks for your answer and also for your concern. I already know the mechanism: with a short pulse, there isn’t enough time for the membrane to depolarize and reach the activation threshold. However, in DBS, the intervals between pulses are also short, so each pulse effect will be accumulated, leadi...

Thanks for explanation.

So in DBS, which the pulses are short, the high frequency is important to the AP generation.

My background is electrical engineering.

My problem is solved. somaL and somaR were in the same locations (I missed the negative sign). I have a conceptual question (Sorry for asking a lot) By setting a pulse duration of 100 ms, I see AP generation. However, if I reduce the pulse width to 0.1 ms, APs are not generated. Is this expected beh...

Thank you for your response. While checking h.psection, I found that the length was incorrect due to a misuse of pt3dadd. Initially, I was using a single coordinate for the entire section. I corrected this by using 21 points, as specified in the hoc file. However, I still do not see an action potent...

Thanks for your answer. I'm starting to model simple neuron and then step by step make it more complex. Right now, I'm using the stimsphere code example. When I run the downloaded example directly as a .py file, it works fine. However, when I use the code below, it doesn't work correctly and just ou...

Good questions. Your instructor/advisor hasn't answered them, or did you ask? They usually don't bite. And if they do, shame on them. Should the extracellular potential be added to all of these compartments or just nodes of ranvier? All compartments, unless your conceptual model includes wrapping th...

Hello, I'm new to NEURON and I'm trying to use this model from modelDB. https://modeldb.science/260967?tab=1 I compiled it with nrnivmodl command. and then I tried to run it with nrngui mosinit.hoc. but I get this error: na is not a MECHANISM in setparam.hoc near line 424 insert na ^ xopen("set...
