(A and B) Electron micrographs showing immunoperoxidase labeling for HA-α2A-AR in somata in the mPFC. HA-α2A-AR immunoreactivity appeared as discrete clumps near the rough endoplasmic reticulum and along the intracellular surface of the plasma membrane (black arrows) in the somata. The intracellular surfaces of somatic plasma membranes were also labeled. These patches of immunoreactive plasma membranes were sometimes associated with synapses. Scale bars, 0.5 µm.
