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)                                         Show

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                                         Show
