Analgesia accompanying food consumption requires ingestion of hedonic foods.

12 Oct 2009 Animals eat rather than react to moderate pain. Here, we examined the behavioral, hedonic, and neural requirements for ingestion analgesia in ad libitum fed rats. Noxious heat-evoked withdrawals were similarly suppressed during self-initiated ... Read more...

Assessing the role of the growth hormone secretagogue receptor in motivational learning and food intake.

29 Sep 2009 The orexigenic neuropeptide ghrelin is an endogeneous ligand for the growth hormone secretagogue receptor (GHS-R). This orexigen is expressed in both the periphery and in the central system, including portions of mesolimbic dopaminergic circuitry ... Read more...

c-Fos expression associated with reinstatement of cocaine-seeking behavior by response-contingent conditioned cues.

29 Sep 2009 The capability of cocaine cues to generate craving in cocaine-dependent humans, even after extended abstinence, is modeled in rats using cue reinstatement of extinguished cocaine-seeking behavior. We investigated neural activity associated with ... 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.
