Microdialysis Probe Placements. Schematic representations
of coronal rat brain sections taken from Paxinos and Watson (1998).
Shaded cylinders depict the distribution of (A) striatal (bregma 1.20
mm) and (B) nigral (bregma −5.30 mm) probe sites in all rats
used in Experiment 2 (N = 26). Relevant anatomical
structures: Aq, aqueduct (Sylvius); Cc, corpus callosum; Cpu, caudate
putamen; LV, lateral ventricle; SNpr, substantia nigra pars reticulata.
