DE animals all ate similar amounts of food when their drinking water was returned, regardless of whether they had been injected with artificial cerebrospinal fluid or NPY into the PVH

Region	Treatment	Amount of Food, g
PVH	DE CSF	6.5±0.5
	3 days DE 119 pmol NPY	7.3±0.3
	DE CSF	6.2±0.4
	3 days DE 238 pmol NPY	6.8±0.3
LHA	DE CSF	6.3±0.4
	3 days DE 119 pmol NPY	5.6±0.6
	5 days DE 119 pmol NPY	7.0±0.5
	DE CSF	6.1±0.2
	3 days DE 238 pmol NPY	6.4±0.4

Values are means ± SE of the amount of food eaten (g) in the 60 min following the return of water to animals given 2.5% saline to drink (DE) for 3 or 5 days, and injected with vehicle (CSF) or neuropeptide Y (NPY) into the paraventricular nucleus of the hypothalamus (PVH) or lateral hypothalamic area (LHA).
