Levels of dopamine (DA), HVA and DOPAC were measured in dorsal striatum tissue by HPLC. Values represent means pM/mg tissue ± standard errors. Dopamine levels were not significantly changed in the ClockΔ 19 mice compared with wild type controls (T(23) = 1.435, p = 0.1646). There were significant differences in the metabolites and metabolite ratios. HVA, DOPAC and the ratio of HVA/DA were increased in the ClockΔ 19 mice (**p<0.01, ***p<0.001, and ****p<0.0001, n = 12–13 animals per group).
