Re: Making nmodl files CVode Compatible

Dear Ted, I followed your advice and I examined the mod files from Mainen ZF, Sejnowski TJ (1996) , but I got surprised when I ran some simulations (while using the mod files from that model) I realized that those mod files are CVode compatible. When I change the numerical method in the Tools menu f...

Re: Making nmodl files CVode Compatible

Dr. Carnevale, thank you for the prompt response! For what I indent to do, I will need a large number of CVode compatible ion channels nmodl files for different single neuron models, and probably it will be time consuming. Are you aware of some CVode compatible ion channels nmodl files that I can ad...

Re: Random synaptic distribution and activation

Dr. Carnevale, thank you for the prompt response! The question I made “asked for a lot”, but I was just curious, and my goals require less: Basically, I am modelling single neurons and I would like to run a few simulation where the simulated neurons have (1) a evenly (or quasi-even) distribution of ...

Random synaptic distribution and activation

Dear all, I would like to know: 1) if there is an out-of-the-box solution, either using the GUI or a chunk of .hoc code, that enables one to randomly distribute a pre-determined number of synapses over a cell’s dendritic tree, and randomly activate those synapses; or, 2) If such solution does not ex...

Making nmodl files CVode Compatible

Dear all, to the best of my knowledge when using the impedance class, the default calculation of the different transfer impedances does not take into account the impedance contributions of gating state differential equations. The calculation is currently limited to systems that can be solved with th...

Print more decimal places

Dear NEURON users!! I am using the impedande class to compute the electrotonic distance of some dendrites. To achieve this I used a slightly modified code from https://www.neuron.yale.edu/phpBB2/viewtopic.php?t=771 . The code I am using is the following: // prepare to use Impedance class // always a...

Re: Printing the final values

I think I figured it out, I just had to add "if (x==1) " after the for (x) statement: // prepare to use Impedance class // always a good idea to finitialize before computing impedance v_init=-65 finitialize(v_init) // demonstrate use of impedance class objref zz zz = new Impedance() FREQ = 0 // Hz ...

Printing the final values

Hello, I am pretty new to NEURON, but I am using the Impedance class tools to analyse the electrotonic structure of some neurons and I am using the following chunk of code to do that: // prepare to use Impedance class // always a good idea to finitialize before computing impedance v_init=-65 finitia...
