Table 4 Partial correlations for performance on 4 neuropsychological tasks reflecting left hemisphere (and cingulate) function and 2 tasks reflecting right hemisphere function with 5-HT turnover (A: 5-HT TR) and the ratio of DA to 5-HT activity (B: HVA/5-HIAA) in patient sub-groups

From: Neuropsychological measures of attention and memory function in schizophrenia: relationships with symptom dimensions and serum monoamine activity
