Electrical coupling between distal apical dendrite and soma. (A) current injections to distal apical dendrite (green arrow) and soma compartments (black arrow) (neuron rendering from Traub et al., 2005) (B, left) model response to 3 nA, 5 ms step current injection into soma when hot zone is in-place. (B, right) Model response to 3 nA, 5 ms somatic step current and EPSP-like current injection to distal apical dendrite (1 nA peak, 5 ms delay relative to somatic step current) when hot zone is in-place. (C, left) Model response to 3 nA, 5 ms step current injection into soma without hot zone. (C, right) Model response to 3 nA, 5 ms somatic step current and EPSP-like current injection to distal apical dendrite (1 nA peak, 5 ms delay relative to somatic step current) without hot zone.
