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...

Factors governing single-trial contextual fear conditioning in the weanling rat.

29 Sep 2009 Although contextual fear conditioning emerges later in development than explicit-cue fear conditioning, little is known about the stimulus parameters and biological substrates required at early ages. The authors adapted methods for investigating ... 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...
