### addng a parameter to mod file

Hi, I am trying to add a parameter that I can change that will affect the kitchens of the channel. **** PROCEDURE rates(v(mV)) { :Computes rate and other constants at current v. :Call once from HOC to initialize inf at resting v. LOCAL alpha, beta, sum TABLE minf, mtau, hinf, htau, ninf, ntau DEPEND...

### Re: Myelin modeling

Hi Ted, thanks for replying to my post. I am trying to model the double cable circuit used by Wårdell et al 2019 with the extracellular mechanism offered by NEURON. I am wondering what is the best approach for understanding what parameters I need to us for the xraxial,xg,xc in order to simulate this...

### Myelin modeling

Hi all this is my code for myelin double circuit model, this is the paranode extntion: h.paranode[1].insert('extracellular') h.paranode[1].xraxial[0]=Rpn1 h.paranode[1].xraxial[1]=Rpn1 newgm=np.divide(gm,(np.array(h.paranode[1].L))) h.paranode[1].xg[0]=2*gm/(np.array(h.paranode[0].L)) h.paranode[1]....

### Re: The math behind extracellular mechanisms

Considering the simplest case, which omits extracellular-- The equivalent circuit of a section with nseg==1 is a T circuit in which all membrane properties (capacitance and ion channels) are lumped into the vertical stem of the T.

### space plot of voltage changes every repetition

Hi all, my simulation does not show the same results for space the space plot, after every repetition. I understand that it is a dynamic system with Fix Points and different trajectories, so the results will not be the same. Is there a way to fix the steady-state trajectories of the system in neuron...

### Save data from a loop in data acquired from neuron

Hi, I am trying to put the values here in an array, and tried different ways in order to implement this. What is the best way to do it? secAIS=h.AIS for seg in secAIS.allseg(): AIS=print('%g %g %g' % (seg.x * secAIS.L, seg.area(), seg.ri())) this code was adapted from here: https://www.neuron.yale.e...

### Re: recording axial current

Record the membrane potential at the centers of the two compartments. After the end of the simulation, calculate the axial current from Ohm's law. Hint: the axial resistance between two adjacent compartments is given by the hoc function ri(). Example: Suppose dend has nseg = 3, and you want to know...

### Plotting the lateral current of any segment

Hi all,
I am trying to plot the overall lateral ionic current flow of my system.
Note I am not trying to plot the membrane current, but the ionic current flowing via the cytoplasm.
