Effect of SN79 treatment on catalepsy. Male, Swiss Webster mice were administered (i.p.) either saline or SN79 (1, 10 mg/kg) and at 0, 10, 20, 30, 40, 60 min after treatment, their front paws were placed on a horizontal rod 5 cm above the bench top, and the latency to return their paws back to the bench top was recorded as an index of catalepsy. SN79 treatment did not significantly differ from the saline treatment. The data are represented as mean ± S.E.M., n = 10 per group
