title: [Nature of the improvement in the modulating influences of the forebrain on cardiac reflexes in a number of vertebrates].
abstract: The analysis of different classes of vertebrates--fish, amphibian and mammalia testifies the forebrain ability to show multidirectional modulating influences on cardiac reflexes already at the early stages of phylogenesis. The perfection of these influences takes place during the phylogenesis. This perfection consists in the appearance of aftereffect and in the increase of aftereffect time. The presence of aftereffect increases the regulatory ability of forebrain. The increase of aftereffect time indicates the tonic character of this regulatory form.
