- Abstract
The effect of an increment in the power of the rhythmic activity of the amygdala during changes in the level of motivation in conditions of the dominance of alimentary or defensive motivation, irrespective of type, was discovered on the basis of spectral analysis of prolonged recordings of electrosubcorticograms of the amygdaloid complexes of three dogs. The resonance characteristics of the system responsible for the generation of this rhythm remain unchanged in the process, which allows explanation of the increase in the spectral peak by an increase in the inflow of afferent impulse activity into the amygdala. Summation of the influences of each of them is not observed in the presence of competing motivations, while a more complex influence on rhythm in the amygdala emerges.
