Neuronal gap junctions in the polymorph layer of the rat dentate gyrus.
In thin sections of the rat dentate gyrus, neuronal gap junctions were observed in the polymorph layer. Gap junctions were seen on dendritic stems, on smooth and/or varicose dendrites, on spine-like appendages, and in one case on a soma. Somata of gap junction-bearing neurons showed indented nuclei with intranuclear inclusions, and received many asymmetrical and a few symmetrical synapses.
