Schematic representation of all injections into the ventral midbrain. Injections that include the PBP or A8 neurons are in dark gray and injections outside these neuronal subpopulations are in light gray. Panels show representative photomicrographs (a–c) of retrograde/bidirectional tracer injections into the DA neuronal subpopulations and adjacent sections labeled with CaBP (a’–c’) to determine boundaries. FR, fluororuby conjugated to dextran amine; FS, fluorescein conjugated to dextran amine; WGA, wheat germ agglutinin-horse radish peroxidase. Scale bar, 500 μm.
