Hi all, I'm trying to output action potential numbers with a series of current injection with different amplitude. Currently I'm using APCount to output the number if spikes as below. objref apc apc = new APCount(0.5) apc.thresh = -12 for i = 0, 20 { stim.amp = 0.1*i run() reci.append(stim.amp) recn...

I suppose it's because the computation is fast enough for their purpose. Not using lookup tables is still fast enough.

Hi Ted, When I modified the TABLE statement with DEPEND like TABLE ninf, ntau, htau FROM -100 TO 100 WITH 200 TABLE hinf DEPEND vhhinf FROM -100 TO 100 WITH 200 I get error message saying 'only one TABLE per function' . I'm wondering where the problem is. Does it mean I should have four separate pro...

Thank you so much for the input! I'm revising my code now.

I figured it out. Just need to set usetable=0. Anyway, thank you very much!

Thank you for your response. But I don't think that's where the problem lies. Even when I add SUFFIX to the parameters except for gbar, the channel behaves the same.

Say I want to change akv1ntaur, I wrote a hoc file called channel_parameters.hoc which includes these parameters, for example //kv1 parameters gkv1bar = 0.0015 vhkv1ninf = -61 kkv1ninf = 14.3 akv1ntaul = 0 bkv1ntaul = 4.59 ckv1ntaul = -56 dkv1ntaul = 15.4 akv1ntaur = 0.21 bkv1ntaur = 5.6 ckv1ntaur =...

Hi Ted,

Do you mind sharing the modified code, please? It seemed that I ran into a similar problem.

Thank you.

Best,

Hi all, I'm new to NEURON and trying to build a one segment model with different ion channels. I'm wondering how to simultaneously change parameters used in mod files in hoc and view plots. As an example, I'd like to change parameters such as vhkv1ninf, kkv1ninf, etc. as in the mod file below. As fo...
