Abstract
To assess the effect of anteroventral 3rd ventricle (AV3V) periventricular lesions on food-associated drinking, the free-feeding patterns of eating and drinking were continuously monitored before and after 14 hooded male rats had undergone lesions or control surgical procedures. Feeding and drinking were monitored with pellet-detecting eatometers and lick-detecting drinkometers. "Recovered" lesioned Ss consumed only half of their daily food and water during the dark portion of the day-night cycle. The strong temporal association between eating and drinking, as well as a normal intrameal pattern of ingestion (i.e., minimal drinking within meals), was evident in lesioned Ss. The positive correlation between meal size and meal-associated water intake characteristic of normal Ss was absent in lesioned Ss. Results suggest that AV3V periventricular tissue is critical for normal body-fluid homeostasis. (30 ref)
