a Proscribed area of CA1 from which Golgi-Cox-stained neurons were selected for analysis. CC = Corpus callosum; DG = dentate gyrus. b Schematic of neuron tracing over Scholl rings with the soma abutting ring 1. The asterisk marks the point of maximal length. The arrow marks the proximal aspect of a third-generation branch immediately after bifurcation from the second-generation branch.
