Concentrations of monoamine neurotransmitters and related metabolites in whole brain. Details of the subjects studied, and statistical analyses, as described in Fig. 2. Abbreviations as described in Fig. 1. Additional abbreviation: 5-HT, 5-hydroxytryptamine (serotonin). Applying our definition of metabolic correction or partial correction (see Materials and Methods), dopamine (iMSUD vs iMSUD-HTx, p<0.001) and 3-MT (iMSUD vs. iMSUD-HTx, p<0.001) were corrected, while DOPAC and 5-HT levels were partially corrected.
