[Dependence of the electrical activity of the amygdaloid complex on motivation level and emotional status in the dog].
On the basis of spectral analysis of prolonged realizations (hundreds of seconds) of electrosubcorticograms of the amygdalar complexes of three dogs, the effect of increase in power of amygdalar rhythmic activity was found, at the change of motivation level in conditions of dominance of alimentary or defensive motivation independently of its kind. Resonance characteristics of the system responsible for the generation of the given rhythm remain unchanged; this allows to explain the increase of the spectral peak by the rise of the inflow of afferent impulse activity to the amygdala. At presence of competitive motivations no summation of their influences is observed; a more complex effect on the rhythm arises in the amygdala.
