Effect of cannabigerol (CBG) on antioxidant defenses in the striatum of 3-nitropropionic acid (3NP)-treated and control mice. Estimation of (A) catalase activity, (B) reduced glutathione (GSH) levels, and (C) superoxide dismutase (SOD) activity. Data presented are the percentage of the vehicle-treated control group and are expressed as means ± SEM for 6–8 animals per group. Data were subjected to one-way analysis of variance followed by the Student–Newman–Keuls test. *P < 0.05, **P < 0.01, ***P < 0.001 when comparing the control group with the 3NP and CBG group. ^# P < 0.05, ^## P < 0.01, ^### P < 0.001 when comparing the 3NP group with the 3NP + CBG group
