Electron photomicrographs showing co-existence of κ-OR and VGlut or CRF in axon terminals in the LC. A. Two axon terminals contain gold-silver labeling for VGlut and peroxidase labeling for κ-OR (κ-OR+VGlut-t). The dually labeled axon terminals form asymmetric synapses (arrows) with unlabeled dendrites. B. An axon terminal containing gold-silver labeling (arrowheads) for κ-OR and peroxidase labeling for VGlut (κ-OR+VGlut-t) forms an asymmetric synapse (arrows) with a dendrite. C-D. Axon terminals exhibiting gold-silver labeling (arrowheads) for κ-OR and immunoperoxidase labeling for CRF (κ-OR+CRF-t) form asymmetric synapses (arrows) with unlabeled dendrites. m, mitochondria. Scale bars, 0.50 mm.
