Abstract
The removal as well as the electro-coagulation of the regions of the brain stem was performed to determine the definite localization of the respiratorycenters. The results are summarized as follows:
(1) At the level of the striae acusticae the normal respiratory centers are located bilaterally and in the group of small cells situated in the lateral reticular formation on both sides. The rostral ends of the centers pass to about 0.5 mm. over the line joining the rostral border of the acoustic tubercles and their caudal ends reach for about 0.5 mm. caudad from the line joining the caudal border of the acoustic tubercles.
(2) It is probable that the centrifugal fibers arising from the normal respiratory centers pass respectively through the lateral reticular formation on the same side and tend to converge as they descend toward the obex.
