Summary
Chronic experiments on cats with the aid of electromyographic methods were used to study the influence of the interoceptive impulse emission on the tonic reaction of the muscles—extensors of the anterior extremities and the neck—occurring as a result of stimulation of the labyrinthine apparatus (rotation of the animal about the bitemporal axis). It was established that the influence of stimulating the interoceptors of the rectum produced a certain activation or inversion of tonic labyrinthine reflexes, which was associated with an increase in the stimulability of the stem centers of these reflexes. In decerebrated animals, the above-mentioned changes in reflexes from the labyrinths to the skeletal muscles in case of interoceptive stimulation were more pronounced. The administration of aminazine caused a sharp reduction both in the labyrinthine reflexes and in the interoceptive influences on them.
