Computer-assisted reconstructions of Golgi-stained pyramidal neurons in layer II-III of medial prefrontal cortex in an untreated and a corticosterone-treated rat. Apical dendritic material is increased proximal to the soma and decreased distal to the soma. Right. Mean intersections of apical dendrites with 10-mm concentric spheres summed across the proximal, middle, and distal third of the arbor for untreated, vehicle-, and corticosterone-treated rats. Vertical bars represent S.E.M. values; asterisks (*) indicate significant difference relative to untreated rats.
