Locomotor activity of CD-1 mice, tested in an unfamiliar environment (toggle-floor box), was increased either by a subhypnotic dose (20 mg kg-1) of pentobarbitone or after recovery from pentobarbitone-induced (50 mg kg-1) anaesthesia. On the contrary, when mice were tested 6 h after a single exposure to the apparatus, pentobarbitone in either case failed to produce hyperactivity. The results demonstrate that mice recovering from barbiturate anaesthesia maintain susceptibility to the exteroceptive stimuli provided by a novel environment and knowledge of the environment acquired during past experience.

Abstract
Locomotor activity of CD-1 mice, tested in an unfamiliar environment (toggle-floor box), was increased either by a subhypnotic dose (20 mg kg-1) of pentobarbitone or after recovery from pentobarbitone-induced (50 mg kg-1) anaesthesia. On the contrary, when mice were tested 6 h after a single exposure to the apparatus, pentobarbitone in either case failed to produce hyperactivity. The results demonstrate that mice recovering from barbiturate anaesthesia maintain susceptibility to the exteroceptive stimuli provided by a novel environment and knowledge of the environment acquired during past experience.File in questo prodotto:
