The code of my model is shown below. from __future__ import division from neuron import h, nrn, gui import matplotlib.pyplot as plt plt.ion() #################################################### Build Model ####################################################### h.celsius = 30 soma = h.Section(name=...

Hi, after learning the 'hh' model of neuron, I learned that there is a bifurcation of electrical response of neurons by the stimuli of current. When current is inscreasing, the voltage of neuron can change from resting potential to activated state. If the current stimuli is big and long enough, the ...

OK. I have read the content of SEClamp in Programmer's guide. And I basically understand how to use it. Thank you very much!

Is this right? I do not know what should I do with current i, it seemed that it does not have to appear in the .mod. COMMENT An event-driven voltage source that delivers an electrode voltage which is changing with x. Arrival of an event with value x instantaneously perturbs the voltage by 1/(1+exp(-...

Hi, I am here looking for help again. What I want to do is add a particular VClamp which is a function of a parameter. The details are shown in the following code. v(t)=1/(1+exp(-6.5(x(t)-1))) x is a variable changing with time(or we can understand that it is a practical physical parameter that we c...

OK! Thank you for your help again. My research is mainly based on extracting useful neural circuit to apply to controlling robot(which is totally different with modern control methods). And the most important work for it is to observe the electrical response of neurons to find an executable control ...

Thank you very much! I have found the source code of expsyn.mod by your instructions. My major is not neural science, and I found that it is trully important to study the fundamental knowledge. Thank you for your advice, again.

Hi, I also found the name of built-in inhibitive synapse function which is h.Exp2Syn() by searching in Github. But I still want to see the source code of them. I do not fully understand where is the on-line help file???

Hi, I found the source code of h.ExpSyn() from the e-mail sent by Ted Carnevale. If there are corresponding inhibitive synapse model, what should I write?

Hi, I want to ask a question about what is the name of built-in inhibitive synapse function in NEURON corresponding with h.ExpSyn()? I tried h.InhSyn(), but it appeared an error. Moreover, where can I read the source code of h.ExpSyn(). I know that the website is provided on the home of NEURON to lo...

Yes! That is what I want. In the past, I do not know about h.NetStim() and its role. While I talked with other person who is also using NEURON, he recommended me this method, too. Thank you for your help really much!!!

Hi, sorry that I am not fully understanding. This is the mod file I tried and you said that do not use "if else" expression, then what should I write? Plus, this stimuli has nothing to do with the synapse which means it does not have relationship with weight. So I changed a little, the num...

and I'll show you how to implement those equations properly in NMODL.

Hi, thanks for your reply. I am really looking forward to your method about how to write in NMODL. Could you please tell me again? Thanks

Thank you very much!!! I have learned your method while I still has a question about NET_RECEIVE module. I have known the information in the following picture from the book <Expanding NEURON’s Repertoire of Mechanisms with NMODL> that for synaptic model building the NET_RECEIVE module can be called ...

OK, I totally understand. For the first question, we are not sure wether "If (v - e) is large and fluctuations of v are small" which means this expression may not be absolutely correct under some circumstances. However, it seems to be appropriate for the form that I need, so I can try it f...
