In an attempt to further define the dopaminergic nature of the limbic nucleus accumbens from the morphologically similar striatal caudate and putamen, the levels of dopamine (DA), homovanillic acid (HVA), and HVA/DA ratios, an index of dopamine turnover, were measured in these three structures of human brain. The levels of dopamine in the accumbens (2.49 ng/mg), caudate (2.39 ng/mg), and putamen (3.00 ng/mg) were similar. The homovanillic acid concentration in the accumbens (7.44 ng/mg) and putamen (6.54 ng/mg) were comparable, while its concentration was considerably lower in the caudate (3.61 ng/mg). The most striking difference between the limbic accumbens and the striatum was observed in the HVA/DA ratio. This index of turnover was significantly higher in the accumbens (3.64) when compared to the caudate (1.80), and was 59% higher than that found in the putamen (2.53). The data provide evidence for differences in dopamine activity in the mesolimbic versus the nigrostriatal pathways.
