Disruption of cue-potentiated feeding in mice with blocked ghrelin signaling

The peptide hormone ghrelin regulates a variety of eating behaviors. Not only does it potently increase intake of freely-available food, but it also shifts food preference toward diets rich in fat, enhances operant responding for food rewards, and induces conditioned place preference for food rewards. Here, we postulated that ghrelin also enables cue-potentiated feeding, in […]

Factors influencing the different performance of fish and primates on a dichotomous choice task

Species vary in the ease with which they can solve apparently similar problems. This can be due to a variety of features. For instance, the ecological context of a problem will be interpreted differently by different species. This could relate to how they interpret the problem, but also, more basically, to which cue they see […]
