Figure 3.

Extracellular noradrenaline (NA) and dopamine (DA) concentrations in the frontal cortex and striatum. All values are expressed as mean ± SEM denoted in fmol 10 µL⁻¹. All results were analysed using two-way anova and a post hoc Bonferroni's test to compare differences between groups (n= 10). (A) NA in the FC; (B) DA in the FC; (C) NA in the STR; and (D) DA in the STR. * Indicates different from sham, P < 0.05. ** Indicates different from sham P < 0.001. + Indicates different from 6-OHDA only, P < 0.05. FC, frontal cortex; STR, striatum.
