Electron micrographs showing immunoperoxidase labeling for dopamine β-hydroxylase (DβH) in axon terminals and immunogold-silver labeling for fatty acid amide hydrolase (FAAH) in the prefrontal cortex. A-F. Dense immunoperoxidase labeling can be seen in a DβH-immunoreactive axon terminal (DβH-t) contacting a FAAH-labeled labeled dendrite (FAAH-d). A-B, D-E. DβH-t forms a symmetric synapse (arrowheads) with unlabeled dendrite (ud). C. A DβH-t that forms an asymmetric synapse (zigzag arrows) with a FAAH-d. F. A DβH-t forms undefined (curved arrow) synaptic contact with MGL-d. Arrows point to immunogold-silver labeling for MGL-α. ut: unlabeled terminal. Scale bars: 0.50 μm.
