Blockade of cue- and drug-induced reinstatement of morphine-induced conditioned place preference with intermittent sucrose intake.

Sep 2008 Sucrose intake has been suggested to alter the expression of morphine-induced conditioned place preference (CPP). To date, the potential effects of sucrose intake on the extinction and drug-induced reinstatement of CPP... Read more...

Heroin self-administration: I. Incubation of goal-directed behavior in rats.

Sep 2008 This study used heroin self-administration to investigate incubation of goal-directed heroin-seeking behavior following abstinence. Male Sprague-Dawley rats self-administered heroin on a fixed ratio 10 (FR10) schedule... Read more...

Role of systemic endocannabinoid CB-1 receptor antagonism in the acquisition and expression of fructose-conditioned flavor-flavor preferences in rats.

Sep 2008 Rats learn to prefer a flavor mixed into a fructose-saccharin solution over a different flavor mixed into a saccharin-only solution which is considered to be a form of flavor-flavor conditioning. Fructose-conditioned... Read more...

Technical information about 'Conditioning, Operant'

Definition: Learning situations in which the sequence responses of the subject are instrumental in producing reinforcement. When the correct response occurs, which involves the selection from among a repertoire of responses, the subject is immediately reinforced.
