Figure 8.
Electron micrographs illustrating selective colocalization of the dopamine D1 receptor, DARPP-32 and I-1in area 9 of monkey PFC. A: Cell soma double-labeled for DARPP-32 (DAB, arrows) and D1 (immunogold, arrowheads, found stereotypically in the Golgi apparatus). B: A dendritic shaft expressing both DARPP-32 (arrows) and I-1 (arrowheads). C: A dendritic spine and shaft single-labeled for D1 (arrows) near a separate dendritic spine single-labeled for I-1 (arrowheads). Scale bar is 500 nm.
