Figure 4. Effects of acute METH and PCP on the locomotor activity in GluRε1^−/− and GluRε4^−/− mice.

Locomotor activity after acute saline, METH (1 mg/kg), or PCP (3 mg/kg) administration (n = 10–25). *p<0.05, **p<0.01, compared with saline (Student's t-test); ^# p<0.05, ^## p<0.01, compared with wildtype (Student's t-test).
