Transfer impedance tool

[plasticity]

I have been using the impedance tool in neuron and would like to understand it’s origin in more depth than appears in the documentation. In particular I would like a better understanding of how the transfer impedance (as calculated by NEURON) follows from the active cable equation and under what assumptions. I have seen links in the forum to old papers by Carnevale but at first glance they do not appear to answer my questions. Does anybody have other reference suggestions?

NEURON calculates the transfer impedances from the model's Jacobian matrix. The Python documentation of the Impedance class goes into a bit more detail about this insofar as limitations of the calculation are concerned.
