Electrical activity of the amygdala and the septum of rats on a high fat or a high protein diet.
The authors studied biopotentials in the region of the amygdala and the septum of rats fed on a standard, high protein or high fat diet. During the first 3-6 days after changing from the standard to the high protein or high fat diet, a decrease in the amplitude of electrical activity was found in both the regions in question. After 3 days on the high fat or the high protein diet, an increase was found in the frequency of electrical activity in the amygdala or the septum, according to the type of diet. A study of the amplitude of electrical activity showed that the electrical potential in the septum was always lower than in the amygdala. The frequency spectrum analysis showed a marked change in the superimposed frequency curve only in animals fed on the high fat diet.
