Concentration of serotonin (5-HT), 5-hydroxyindolacetic acid (5-HIAA) (a, b) and 5-HIAA/5-HT turnover (c) in respective left (L) and right (R) brain structures (striatum and brainstem) in sham and 6-OHDA treated rats evaluated by HPLC detection ex vivo. All values are means ± SEM. *P < 0.05, **P < 0.01, ***P < 0.001, comparison between sham and 6-OHDA treated groups (n = 8–9/per group)
