[Role of the ventromedial nucleus of the hypothalamus in regulating feeding behavior in Landes geese].
This study shows the apparent role of the ventromedial nucleus of the hypothalamus (VMH) in regulating food intake in the goose. The feeding pattern of normal animals has been compared with that of animals made hyperphagic by destruction of the VMH. Lesioning of the VMH modified the circadian pattern of intake. All the geese tended to equalize their intakes between the light and dark periods. The overall effect of lesioning was considerable hyperphagia resulting from an increase in the number of meals and of their amplitude and duration, as well as in the rate of ingestion. We have emphasized the importance of defining the meal when interpreting changes in the correlations between the amount of food ingested during the meal and the length of pre or postprandial intervals after destruction of the VMH. Although it is important, the fatty liver syndrome induced after hyperphagia is not sufficient to produce fatty livers which can compete with those obtained by traditional cramming.
