abstract：:Bilaterally symmetrical periventricular lesions at preoptic-anterior hypothalamic levels of anteroventral third ventricle (AV3V) produce adipsia without aphagia in the rat. Sweet palatable fluids, but not water, are drunk during the adipsic period and if hydration is thus maintained, voluntary ingestion of plain water...
