Dailey MJ, Bartness TJ (2010) Arcuate nucleus destruction does not block food deprivation-induced increases in food foraging and hoarding. Brain Res 1323:94-108. doi: 10.1016/j.brainres.2010.01.078
Summary: While some aspects of food intake are understood, mechanisms controlling hoarding of food have not been identified. This work investigates the role of NPY in the arcuate nucleus (Arc) in hoarding. Siberian hamsters received 48 ng injections of NPY-SAP (Cat. #IT-28) into the Arc; blank-SAP (Cat. #IT-21) was used as a control. In lesioned animals food deprivation-induced hoarding was increased 100%, but baseline foraging and food hoarding was unchanged.
