Hippocampus CA1 pyramidal GLU cellProximal apical dendriteI L high threshold.Using a monoclonal antibody (Westenbroek RE et al, 19901 ). showed that the proximal dendrites and somata of hippocampal neurons label for L-type Ca2+ channels and that these channels tend to cluster near the bases of the neural processes. In patch recordings, "HVA-l channels reminiscent of L-type channels were occasionally encountered primarily in the more proximal dendrites" (and in the soma) (Magee JC and Johnston D, 1995 [rat]2 ). Ca fluorescence imaging shows that application of L-channel antagonists reduces the Ca influx associated with backpropagating action potentials, and has a significantly greater effect in the proximal dendrites than in more distal dendrites (Christie BR et al, 19953 ).
