FIGURE 4. Methylphenidate treatment for eight days mimics amphetamine-induced alterations in phosphorylation of Akt and GSK3 in the striatum.
A. Treatment with 20 mg/kg methylphenidate for eight days reduced striatal phosphorylation of Thr308-Akt and Ser473-Akt. B. Phospho-Ser21-GSK3α and phospho-Ser9-GSK3β were reduced in striatum after methylphenidate treatment for eight days. Values are presented as percent of matched control mice. Means ± SEM. n=3. *, p≤0.05.
