solving differential equation describing Vm

Hi All, I am trying to understand how NEURON calculates membrane potential, but for some reason, I cannot figure it out. I have created a very simple model, with a single compartment proc celldef() { topol() subsets() geom() biophys() geom_nseg() } create soma proc topol() { local i basic_shape() } ...

Re: Fitting the output of the Linear Circuit Builder

Thanks for the quick reply! The first part is understood, I could make it work this way. The second part, dealing with the 13 RC components is however not an MRF bug. This happens whether or not I fit anything. This problem persists even if nothing is open, but the LinearCircuitBuilder itself. I hav...

Fitting the output of the Linear Circuit Builder

Dear Ted, I encountered a problem when fitting the voltage-response of a node with the multiple run fitter. I could do everything as expected until a certain point, which was the implementation of more than 12 parallel RC components into my reduced circuit. After the 13th, the Linear Circuit Builder...

Current clamp circuit with capacitance compensation

I am trying to create a current clamp circuit with bridge balance and capacitance neutralization. Luckily I was able to get a version of older demos, including init_r_comp and init_rc_comp3. Further on, my questions will be about init_rc_comp3, as I was unable to fully understand how this circuit wo...

Transient potassium current as leak

Hi Ted I apologise in advance if my question is being posted in wrong place. My problem concerns a transient potassium current which is extremely low-voltage activated, and I created the MOD file based on my experimental data. So when I want to insert this mechanism into my reconstructed cell, it un...

Making a delay in the activation of an ionic current

Hello! I am currently doing a model on reproducing the firing of my recordings from interneurons. The main concenpt of this model is to see, how A-type potassium channels creates a delay in the firing, with the appropriate kinetics. In my recordings, the current does not activate until 1-2 ms after ...
