Figure 2From: SERT-to-DAT ratios in early Parkinson’s disease do not correlate with the development of dyskinesias Correlation between serotonin and dopamine transporter binding. Serotonin transporter binding (BPND midbrain) is significantly correlated with dopamine transporter binding in the most affected putamen (BPND putamen most affected side, left panel; r = 0.496, P ≤ 0.001) and striatum (BPND striatum, right panel; r = 0.532, P ≤ 0.001).Back to article page
