Flourens, Longet, on the basis of studies carried out at different levels of the central nervous system, put forward a hypothesis that in the medulla oblongata, corresponding to the X level of the pair of cranial nerves, there is a point - "noeud vital" - vital node 1 mm in size, damage to which is instantly accompanied by respiratory arrest. But searches for the anatomical localization of this node were in vain, and the question of the source of stimulation of respiratory movements was not resolved either.</p>Kazan Medical archiveКазанский медицинский архив
