Fitting the dV/dt vs V plot
Posted: Mon Mar 10, 2008 5:24 pm
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) as long as I am dealing with a single compartment, which is my case. In fact, I can do a very nice phase plane plot of my simulated action potentials. But I can not see how to creat a Fitness Generator with it.
What kind of Generator should I use? specially, I don't know how to specify a fitness generator in which the x variable is not time.
Thanks in advance for your answers!!
