Hello, Is there any way to change membrane resistance/capacitance values during run time? My simple thinking was to add a condition if (t >= time_of_interest) then change membrane resistance end With my custom NMODL mechanisms I can do that by just adding the condition to MOD file, but what about HOC?

Hi, I have another question related to the longitudinal diffusion. I would like to monitor the ion concentration change incurred by longitudinal diffusion of specific ion to and from the specific section. If I only had longitudinal diffusion mechanism in this section, I would simply compute this cha...

Hi, 1) Thank you for pointing out the correct terminology - indeed it's "transport" and not "diffusion", I should have remembered that.... 2) Thank you for the answer (even though it says it's impossible to tackle the question I asked) - good to know that these issues are importa...

Thank you! The syntax is clear now, although I still wondering - would the diffusion process be the same if (a point) source is in dend[0] or in dend[1]? Question number 2 (and maybe it's related) - what would be the way to model one way diffusion (I know strictly speaking it should not be called di...

Hi Ted, Is there any short and convenient way to model longitudinal diffusion with location-dependent diffusion coefficient? In general, how does the NEURON treat situation in which two connected sections each have the same mechanism of longitudinal diffusion, but with different diffusion "cons...

Hello, I want to simulate synaptic stimulation with the pattern of stimulation that depends on some conditions at the moment. That is, something like this - 1. At time t_1, stimulate with N_1 pulses at frequency f_1 2. At time t_2 (t_2 sufficiently larger than t_1 not to overlap with earlier stimula...

Hi, I have a datafile for 3D reconstructed neuron (the tree is defined with "pt3dadd" commands). What I would like to do is to "clone" the specific branch (with all its sub-branches) of this given tree. That is, I want to create a new tree in which, at a specific point, there wil...

Continuing the theme - is there an easy way (in ~ one line of code) to know how many point processes of particular type are present in particular section ?? I know it's possible just to go over all the point processes with MechanismType and count them, but a one built-in function would be much more ...
