Hi, I have followed your example of ring network in the paper "Translating Network Models to Parallel Hardware". I see that for the NetStim connection to the first cell is made through NetCon and the rest of the cells are connected through gid_connect. I am not sure why NetCon was used for...

Hi,

Can anyone kindly help me overcome this problem?

Please let me know how to solve this.

Thank you.

Hi Ted, Thank you very much for explaining clearly. I have changed the name of the mod file as you have told. I understood that in the NET_RECEIVE block, I cannot give two WATCH statements without the net_send statement to force the threshold for bringing the membrane potential back to the resting v...

Hi, I am working with a mod file with all the parameters and values to simulate a simple point process model. I find that I have to call net_send(0,1) twice for the mod file to work. The initial call net_send(0,1) in the INITIAL block takes you to WATCH statement block but after resetting, I had to ...

Hi, I have tried a lot installing pyNEURON on windows and it seems to be working but not as easily as with Linux. Firstly, there is no correct instruction on how to configure NEURON with Python. I have tried installing through executable (.exe) file but it says libnrnpython34 is not available. I hav...

Hi Ted, I am providing the scripts of each file I used. The scripts are as follows: 1) Pregen.mod (SpikeGenerator mod file). 2) adex.hoc (template creation of spikegenerator) 3) cells_test.hoc (creating the cells) 4) modifycheckmoss.hoc (main file for changing the file parameters during run) : $Id: ...

Hi Ted, I have tried your advice but I couldn't turn the stimulus on after I called stdinit(). Somehow, the stimulus is turning on only when it is called before stdinit(). When I try to use it after the stdinit() call, it doesn't work. Is there a reason that the <proc> functionality doesn't work whe...

Hi Ted, Sorry for not mentioning the spikegenerator properties. Yes. The presynaptic events happen at random times. I have used a random function to generate events between t and t+DUR. I have not used NetStim and VecStim to play the spike events. objref rand_mos rand_mos=new Random() mossyfiber.spi...

Hi Ted,

This is a single simulation with different set of mossy fibers being activated at different intervals.

Kindly let me know how can I solve this?

Thank you.

Hi Ted,

Yes. I am trying to do multiple continuerun statements for activating different mossy fibers in each run.

Kindly let me know how can I solve this?

Thank you.

Hi, I have been trying to use multiple continuerun() statements inside run block to simulate the mossy fiber on and off conditions. In my case, I would like to run the simulation for 5 seconds and for each second, the activated mossy fibers (spikegenerators) will be different. The end parameter of t...

Dear Ted, I have sent you the email with the code on Nov 3 but I am not sure why it isn't delivered. And I found the error in the code after going through several posts in NEURON forum and rectified it. It resulted mainly due to faulty conductance value. Thanks a million for your kind help and respo...

Hi Ted,

I am using NEURON 7.4 for all my simulations.

I am sending the compressed code to your email.

Kindly let me know where I'm going wrong in my coding.

Thanks.

Hi, I was using nc.record function for artificial neuron models. Where I simulated 30 neurons, there is no error but when I increased to 31, it pops up an error: "abandon when t==qthresh_->t_=" Segmentation violation CVode[0].use_daspk(1) NumericalMethodPanel[0]. isdaspk() NumericalMethodP...

Thanks a lot Ted. Will do that and see if I can figure out.
