...we built a multicompartmental model with a morphologically realistic three-dimensional reconstruction of a CA1 pyramidal neuron. The only active conductance we added to the model was the h conductance. ... We conclude that experimentally observed gradient in density of h channels could theoretically account for experimentally observed gradient in resonance properties (Narayanan and Johnston, 2007).

The impedance related measurements that would be obtained from the
traces in the Output directory (for Chirp responses across the
trunk) are listed below. The first column is the radial distance
of the trunk compartment (um) that is being assessed, followed by
resonance frequency (Hz), resonance strength and maximal impedance
amplitude (M.Ohm), in that order.
