Summary In a large number (91) of vervet monkeys, correlation coefficients were determined between homovanillic acid (HVA) concentrations in four brain areas. Significant correlations existed between dorsal frontal cortex and orbital frontal cortex and between putamen and caudate nucleus. However, no significant correlations existed between either cortical area and the basal ganglia areas. Correlations were tested between CSF and plasma HVA and between these fluids and brain regions. The only significant relationship found was between CSF and dorsal frontal cortex, after possible treatment effects were statistically removed. The assumption that primate CSF HVA concentration necessarily reflects basal ganglia HVA concentration is questioned and furthermore, the results suggest that HVA from cortex contributes significantly to that in cisternal CSF. Raw plasma HVA measurements (even when uninfluenced by diet or anesthetic) appear to be of limited value in gauging central dopamine metabolism and turnover.
