psection-like dump of global parameters

Hi, Is there a way to dump the global parameters for all the inserted mechanisms and processes? psection() only dumps the RANGE parameters (otherwise it wouldn't be called p section () ). Moreover, I would like to produce such dump without having to know a priori which mechanisms/processes are inser...

Have you examined the time course of cai in a constant diam model whose diam is the same as the smallest diam in your variable diam model? Indeed I have, and the result is the same as in the narrowest section of the model with variable diameter. In other words, the steady state cai is highly depend...

Calcium difusion and buffering with variable diameter

Hi, I am using the calcium diffusion and buffering mechanism presented as Example 8 of the NMODL expanded documentation, with the additions specified in the Example 9 that add a calcium pump (the complete code is below). In addition, I have an L-type calcium channel mechanism which provides some cal...

Very interesting suggestion, specially the one about the polar coordinates. I will try it and see what happens.

Thank you!!

Fitting the dV/dt vs V plot

Hi, I'm trying to reprouce the shape of an action potential, and in order to make a better fit I want to fit the dV/dt vs V phase plot, in addition to (or instead of) the common V vs t plot. If I understood well this thread , I can easily obtain dV/dt by plotting i_cap (capacitative membrane current...

TABLE command

Hi, I usually see the TABLE command, such as in PROCEDURE rate(cai(mM)) { TABLE zinf, tauz FROM 0 TO 0.01 WITH 300 UNITSOFF zinf = cai*cai*cai*cai / (cai*cai*cai*cai + 8.1e-15) (...) tauz = 1 - (186.67 * cai) (...) UNITSON } (This is a random example that I picked from elsewhere with non-relevant co...
