Hello Ted, I solved the issue, I was using multiple scripts and something went wrong in the order in which I called it, now I don't get any more errors. However I had a question, I want to save the data to be read in matlab from your earlier code to automate the postprocessing of recorded currents. ...

Hello Ted, thanks for your solution, but I am facing another problem now which didn't happen before. I get the Segmentation violation error when I use run() after I insert the xtra mechanism . I tried forall and forsec cellsections (with either of the methods that you suggested) both gave me the sam...

Hello Ted, I get the following error when I try to implement the code with a preexisting model: extracellular mechanism not inserted in section xScale However if I go to the GUI and view inserted mechanisms xtra is present. I am not sure what I am missing. I also tried with xtr.mod, same error. My a...

Hello Ted,
Thanks for your reply. The superposition worked, I can now get both stimuli working together. For after solve I used the same statement from xtra.mod as I had dissociated stimulation and recording electrodes. So a single recording electrode works for my purpose.

regards.

Hello Ted, I wanted to create 2 instances of monopolar stimulating electrode and 1 instance of recording electrode. I modified the xtra.mod file as follows: NEURON { SUFFIX xtra RANGE rx, er, rxstim1, rxstim2 RANGE x, y, z GLOBAL is, isap POINTER im, ex, exap } PARAMETER { : default transfer resista...

Hello Ted, thanks for the clarification, they was some problem in compiling the mod file as a point process. Its been sorted out now. Still getting used to the some of the hoc syntax. Now am able to implement the extracellular stimulation and recording code to the CA1 neuron I am using for my experi...

I went through the hoc files along with xtra.mod including setpointer.hoc. I wish to know if fsin.mod is to be treated as a mechanism or point process? either way I keep getting syntax errors. I cannot figure out what I am missing yet.

thanks,
regards.

sorry a correction in the code:
thanks,
regards

Hello Ted, I tried using the fsin.mod file to generate the sinwave to be used as input to the extracellular stimulus recording program using the initxstim.hoc. However I am not seeing a response. I cannot figure out where I am going wrong. I understand that Pointer "x" in fsin.mod passes t...

thank you Ted.

Hello Ted, I am trying to implement the extracellular stim and rec on Poirazi's model. I need to give a sinusoidal stimuli on selective segments, if possible could you post the mod file you mentioned earlier along with the instructions to link it to xtra's stimulus current variable. For this, better...

The problem still persists with the latest alpha version too.

Am using NEURON Version 5.8.88

I have been trying to use the network builder to connect two neurons. The model neuron oscillates spontaneously when it is dragged into the network layout field and run after toggling the create button on. Once I attach a synpase (synaptic conductance and other synaptic parameter values are zero) an...
