Hello everyone. I have question about making computational neuron models. What is exact input impedance value or range for simple and full morphology models? In my experience, input impedance matching was most important in order to change full morphology neuron model to simple neuron model. I think ...

Hello. I tried to make network model between CA1 neuron model and my neuron model. 1. Copy the source that Migliore CA1 pyramidal neuron model in ModelDB. 2. Modify the source(Migliore CA1 Pyramidal NEURON source, remove Clamp) 3. Make Template my neuron model begintemplate myec public exp2, soma cr...

I used several channels in modelDB to optimize simulation result. Channel conductance was changed for result. So, conductance values not equal to original model and also channels were mixed by few models. Finally, I get the similar result. but I have a question. Are these conductances reliable? Are ...

Thanks for your answer. I don't have biology experiment result. Just i have graph result in the paper. Multiple Run fitter must need experiment result data. Is it possible to make neuron model with graph result in paper? How could i transfer graph result to file? I am novice user. If my question was...

Hello. I would like to know about how to fit neuron output through biology experiment result. Actually, I want to made slow depolarization and delayed spiking neuron model. But it isn't easy to me. I used many neuron model in modelDB. but, I couldn't success. So, I would like to know that is it poss...

We should turn on the value of LTP and LTD. These values are turns off basically in the mod file. sy = new ExpSynSTDP(0.5) sy.d = 1 : LTD sy.p = 1 : LTP This is my example source code. load_file("nrngui.hoc") create soma soma { nseg = 1 diam = 18.8 L = 18.8 Ra = 123.0 insert hh } proc init...

Yes, Ted. It's very similar. set the second spike time from without IPSP stimulate simulation. ( I use IClamp for inject similar IPSP. ) for i=0:windows set IPSP.del = second spike time + ( i * (Inter Spike Inter/windows)) set IPSP.amp and IPSP.dur run a simulation observe the third spike end this i...

Hello. Ted. I always thank you for your answer. I have a critical problem. My simulation conditions are below. - Two IClamps - Step Current(1000ms) - IPSP Current(5ms, different delay each simulation after 2nd spike) - One Izap Stimulation - Sinusoidal Conductance(1.5nS, 5hz) - full morphology neuro...

Hello, Ted I always thank for your answers. I've got a some question. I wonder about "how do i control the rebound current amplitude?" I used this h-channel model. TITLE I-h channel from Magee 1998 for distal dendrites UNITS { (mA) = (milliamp) (mV) = (millivolt) } PARAMETER { v (mV) ehd (...

Thanks! Ted! it has been work well!!

hello. I have benn setup NEURON 7.1 version dmg file. (my os version is mac osx 10.6.4) and I try to drop down myproject folder in mknrndll for compiles. I have got this error message. (this project is well done in windows version.) /Applications/NEURON-7.2/nrn/umac/bin/nrnivmodl: line 149: make: co...

Where did you expand izap.zip? Did you expand it into a subdirectory of c:\nrn7.1, or did you expand it into some other location?

Thanks Ted. I did expand Izap.zip in c:\nrn7.1.

I hope to solve this problem.

Thanks for your quick answer! Did you compile the mod file? Yes, I have done compile sucessfuly. Exactly what did you do to "execute initizap.hoc"? I had double clik initizap.hoc file. So, a few windows come out throught this windows I can check sinewave in windows 7. But 2008 R2 isn't. Wh...

Hi, all I have finished installation Neuron 7.1 at Windows server 2008 R2. I think that it is not a problem at all. because I used Neuron 7.1 at Windows 7. But, I met some problem. some project source isn't work! example) I execute initizap.hoc. then, Neuron windows come out and just disappear. nrng...

Hello, Ted I have solved this problem. but There are still a little problem. I try remove NEURON 7.1 and then I have start from the beginning. I had completed setup and copied Izap directory(c:\nrn71\chals\Izap). then I try modlunit,mknrndll. I had success Izap setup. After execute initizap.hoc, I c...
