Electron micrographs in the PFC showing TH-labeled terminals that form distinct synaptic contacts with PRV-immunoreactive dendrites. In A and B, a TH-labeled terminal (TH-t), shown in serial sections, forms a symmetric synapse (curved arrows) on a PRV-labeled dendrite (PRV-d). C and Dshow two additional examples of PRV-labeled dendrites that receive symmetric synaptic contact (curved arrows) from TH-labeled terminals. Scale bar, 0.25 μm.
