Re: loop structure

Dear ramcdougal, Thank you so much for your reply. I used the following code. I can save all the data for every run, but the problem is all the data save in a single file. I want to save data of each trial in a separate file. Would you please help me to do this? Thanks objref ivec, tvec, vvec ivec =...

loop structure

Hello all,
I give my neuron a noise input to soma and an extracellular constant current and repeat this process for 100 trials. I'm trying to do this with "loop" structure and save Vm and Ve and current data for each trial. Would you please help me how can I do this?
Thanks

theoretical and simulation results of applying uniform electric filed

Hi all, I have a simple passive cable model of dendrite. I used the codes of extracellular record and stim with a monopolar electrode. I put the electrode far from the end of the cable. I mean the cable is horizontal with the length of 500um, and the electrode location is (6000,0,0) , so I have a un...

Re: apply extracellular electric field and current

Hi all, I used the codes in extracellular record and stim to stimulate my simple neuron model with intracellular and extracellular current. I have some questions, I will be grateful if answer them: 1) I used "record" as follows but still I can't calculate intracellular potential... //record membrane...

Re: Action Potential propagation

Dear Ramcdougal,

Thank you so much for your reply and your recommendations.
Would you please answer my 3rd question, too?
If I insert extracellular to my model, I have extracellular potential, haven't I?
If so, how can I code for intracellular voltage?

Thanks

Action Potential propagation

Hi, I have 3 questions: 1: Would you please tell me, the model that NEURON uses is always based on cable theory ? Can we have point model of neuron ,too? 2: I wrote this code: create soma, axon access soma soma.nseg = 1 soma.diam = 18.8 soma.L = 18.8 soma.Ra =123.0 soma insert hh soma psection() axo...

apply extracellular electric field and current

Hello I am new NEURON user and I apologize you for my elementary questions... I want to study the response of cable model of neuron (with considering diffusion) to: 1. uniform extracellular electric field , 2. time variant extracellular electric field, 3.pulse of electric current and 4.temporal osci...
