P>The dendritic arbor is the site of complex interactions between synaptic excitation and intrinsic excitability. This interaction is determined by the ion channels expressed on the dendritic arbor. The expression and gating properties of these channels can be perturbed in conditions associated with epilepsy that lead to hyperexcitability.
