Figure 3
Effects of repeated administrations of saline or 1βmg/kg of NIC (a), 10βmg/kg of BUP (b), or 4βmg/kg of MP (c) to the same ICR mice on ambulatory activity. The administration was repeated 5 times with intervals of 3-4 days. Symbols represent mean values of ambulatory activity for 60βmin periods after the administrations, and vertical lines indicate SEM.
