Figure 2: The treatment with valproic acid (VA) reverses the decreased locomotor activity (a) and rearing behavior (b) of the untreated 6-OHDA group, whose values go towards those of the sham-operated control (SO). Values are mean ± SEM from 5–8 animals per group. (a) a. versus SO, , ; b. versus SO, , ; c. versus 6-OHDA, , . (b) a. versus SO, , ; b. versus SO. , ; c. versus 6-OHDA50, , (two-tailed Student’s -test).
