Differential filtering of somatic and dendritic input persists for a variety of cell morphologies and a gradual distribution of the active current.

<p>Q-values of the dendritic input impedance (blue), somatic input impedance (red), and dendro-somatic transfer impedance (black). <i>a</i>: The default model from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0078908#pone-0078908-g001" target="_blank">Figures 1B</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0078908#pone-0078908-g002" target="_blank">2C</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0078908#pone-0078908-g003" target="_blank">3</a>, and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0078908#pone-0078908-g004" target="_blank">4</a> (length of passive cable m, length of active distal end m, dendrite diameter m, peak conductance in active segment nS). <i>b</i>: Tapering of diameter towards the dendritic end (dendrite diameter gradually decreases from m to m). <i>c</i>: Neuron with two dendrites, both with the same parameters as model <i>a</i>. <i>d</i>: Branching neuron (length of primary dendrite m, length of passive parts of both daughter dendrites m, length of active dendritic ends m). <i>e</i>: Uniform distribution of h-conductances (peak conductance density mS/cm). <i>f</i>: Exponential distribution of h-conductances (S/cm). Note that the total h-conductance and the length of the path between distal dendritic end and the soma were the same in all considered cases.
