According to some investigators, tonus of sympathetic nervous system is not observed at all or marked a little, according to others--it is marked well. Tonus of sympathetic nerve has not been discovered at all in our experiments. The experiments have been made on narcotized and non-narcotized pigeons, guinea pigs, rats and dogs. The frequency of heart beats is regulated by n. vagus and humoral substances in rest.
