The organization of the central nervous system mechanisms involved in respiration in the albino rat as shown by electrical stimulation and surgical transection is similar to that in other species previously studied. Areas of the medulla producing inspiratory or expiratory movements on stimulation are distinct and separated. The inspiratory center occupies about 1.1 cu mm on each side and overlies the rostral one-third of the inferior olive. The expiratory center is somewhat more diffuse and lies dorsal and caudal to the inspiratory center. Serial transections produce the usual phenomena which lead to the identification of the pneumotaxic center and apneustic center. In the medullary rat ataxic breathing shows a dissociation of the inspiratory-expiratory sequence in breathing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
