Resumo The effects of paradoxical sleep deprivation (PSD-48 h) on the conditioned and unconditioned components of behavioural sensitization to amphetamine (two injections of 2.0 mg/kg, separated by 7 days) were studied using locomotion frequency of mice observed in an open-field as experimental parameter. Behavioural sensitization only occurred in PS deprived mice that were exposed to the open-field after the first amphetamine injection. the possible involvement of PSD in the development of a Pavlovian association between the stimulant effect of amphetamine and environmental as well as interoceptive drug cues is discussed.
