In acute experiments on monkeys studies have been made on the character and functional properties of the EP as well as of extracellular neuronal reactions in the new cortex zones during stimulation of phylogenetically different parts of the hypothalamus. It was shown that most short-latency, low-threshold EP and neuronal responses in the new cortex of the monkeys are recorded during stimulation of the posterior and lateral hypothalamus. It was also demonstrated that the focus of maximum activity of short-latency evoked reactions is localized in the frontal associative cortex. Differences in the effects of the posterior and lateral hypothalamus on the new cortex in monkeys are discussed.

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.
