Figure 1.

Tonic extracellular levels of DA and its metabolites are altered in ErbB4 KO mice relative to WT controls. Tonic extracellular levels of DA, DOPAC, and HVA (panels on left), and unilateral or bilateral location of probes used for microdialysis (schematic depiction on right), are shown for the (A, B) dorsal striatum, (C, D) medial prefrontal cortex, (E, F) dorsal hippocampus, and (G, H) NAc of ErbB4 KO (KO, blue; n = 6–7) and control (Ctrl, black; n = 6–7) mice. Data are expressed as the mean ± SEM; **p < 0.01.
