Summary: | The authors studied bioelectric potentials in the area of the hypothalamic ventromedial nucleus and the lateral hypothalamus of rats fed on a standard, a high protein and a high fat diet. On the first 3--6 days after changing from the standard to the high fat and high protein diets, a decrease in the amplitude of electrical activity was recorded in both the areas in question. It was also found that the frequency of electrical activity in the hypothalamic ventromedial nucleus or the lateral hypothalamus rose, after 3 days administration of the high fat or the high protein diet, in correlation to the type of diet, and that, in the frequency spectrum, a change occurred in the proportion of basic frequency in relation to superimposed frequencies distorting it. It was further found that there was a permanent difference between the amplitude of electrical activity in the lateral hypothalamus and the hypothalamic ventromedial nucleus. |
