Omel’chenko O. Amygdaloid complex of Limbic system in organization of motor component of behaviour reaction

The dissertation is devoted to study of role of the basolateral amygdala in organization and control of automated food-getting movements of forelimb on rats. There were used methods of fotorecording, sighting brain destruction, registration of impulse neuronal reactions by free behaviour. It has been shown that destruction of the basolateral part of amygdala leads to breach of the food-getting movements. The movement’s duration increased, frequency decreased and number of trials, necessary to get a food globula also increased after destruction of the basolateral part of amygdala. Especially considerable changes of movement’s parametres took place in the second half of 10-minute experiment. The results of electrolytic destruction of the basal amygdaloid nuclei were different from the results of destruction both basal and lateral nuclei of amygdala. An increase of movement’s frequency and decrease of its duration were observed. Took place shorterning of duration of all movement’s phases. The resultsare witness of the inhibition function of the basal nuclei of amygdala. It has also been shown participation of the basal amygdaloid nuclei in the rearrangement of motor programs.
