Interrelation between Sympathetic and Parasympathetic Cardiac Nerves within Ontogenesis.

摘要

ABSTRACT We have studied the formation of interrelation between sympathetic and parasympathetic influences on the heart in dogs and rats in ontogenesis during electrical stimulation of nerves. To achieve the tasks set we have carried out acute experiments on adult dogs and puppies of the first, second and third age groups using artificial respiration, as well as on intact and sympathectomized growing and adult rats with natural respiration. The basic principle of interrelation in adult animals .
