Thanks for your answer. I often see models in which a gigantic stimulus is used to elicit a spike--a stimulus large enough and long enough to contaminate the resulting action potential at the spike trigger zone. Is that what's happening with your model? I use different types of stimuli but the most ...

Dear Ted, I apologize for the late answer. Thanks for your explanations on the HH mechanism. I ran hundreds of tests to make sure that each step was operated properly. And I also re-read Rattay et al 2001, Hear Res. I made sure the geometry and biophysics of my model was exactly as in their study an...

Thanks for your answer. Here are details on the cell topology: [node-internode-...-node-Soma-node-internode...-node] soma: diam =30, L =20µm central axon : - diam = 2 µm - 11 nodes, L = 1.5 µm - 10 internodes, L = 100 µm peripheral axon : - diam = 1 µm - 6 nodes, L = 1.5 µm - 5 internodes, L = 100 µ...

Hi all, I am trying to simulate a linear fiber with a central axon, a soma and a peripheral axon. I used the dimensions given in Rattay et al, 2001, Hear Res.: central.diam=2 um, peripheral.diam=1um, soma.L =20 and soma.diam =30. However when using these parameters I am facing unexpected behaviors: ...

Thanks, I'll have a close look at it.
Best,
Quentin

Dear Ted, thanks for your help I checked the Model View and found nothing surprising. But I think I have identified several sources for my issues. 1/ I used values for gna_bar that were too low which I think are responsible for these periodic spikes. 2/ Once this problem solved I tried to implement ...

Dear Ted, thank you so much for your reply. To make sure I did everything the right way I started all again from the very beginning as in the example you propose for beginners. I implemented a simple cell (one soma + one dendrite both with HH behaviors) and it seems to be a more general issue: When ...

Dear all, I am very new to Neuron and I also am facing troubles using extracellular stimulation. My goal is to evaluate the influence of various electrical stimuli (monophasic, biphasic, pseudo-monophasic... pulses) on a very simple model of an auditory nerve fiber. To do so I started studying the e...
