They found that ghrelin (a gut-derived orexigenic hormone) delivery, significantly enhance an animal amount of work to obtain sucrose (carbohydrate found in many plants and plant parts) reward. They also argue that their findings are paired with the hypothesis that an essential role of the central ghrelin signaling system is to increase the motivation of rewards, including food.
