[Interaction of brain structures regulating the vocal and respiratory systems].

Unit activity data revealed an obvious interrelationship between the brain vocal and respiratory systems. Modification of evoked reaction of the vocal system depends on stimulated central nuclei and parameters of stimulating electric current. The threshold of evoked vocal reaction is higher than the threshold sufficient for modification of respiration and neuronal activity. The data obtained suggest that not all the structures related to the respiratory regulation bear control over the generation of species specific cries.
