[Organization of the hypothalamo-amygdalar system in rats].
In acute experiments on rabbits, the ascending influences of phylogenetically different parts of hypothalamus on different nuclei of amygdala were studied with the aid of EP method. In mammals a certain type of organization of hypothalamic ascending connections with amygdala was found. It was shown that phylogenetically ancient--anterior--parts of hypothalamus are projected mainly onto the oldest (cortico--medial) division of amygdala, which is the olfactory center of the forebrain. On the other hand, phylogenetically younger nuclei of hypothalamus are functionally connected with young parts of amygdala (basolateral division) which are the important regulatory component of limbic system. The properties of functional organization of hypothalamic--amygdaloid system of integration in rabbits are discussed.
