Inspiratory neuron

Japanese: 吸息性ニューロン - きゅうそくせいにゅーろん
Inspiratory neuron

…A large number of respiratory neurons are distributed in the reticular formation and its surrounding areas in the brainstem. The first theory considers that the area where the respiratory neurons of the reticular formation in the medulla oblongata are distributed is the localized area of ​​this mechanism. The second theory considers that the location of this mechanism is both a narrow area (dorsal respiratory group, DRG) in the dorsal part of the medulla oblongata where inspiratory neurons, a subgroup of respiratory neurons, are gathered, and a localized area (ventral respiratory group, VRG) in the ventral part where inspiratory neurons are gathered at the top and expiratory neurons are gathered at the bottom. Recently, research has been done on the presence or absence of respiratory rhythm when the localized areas of the DRG and VRG are locally destroyed in animals, and it has been confirmed that the respiratory rhythm continues even after the function of the neuronal groups in both areas is lost. …

…脳幹部には網様体とその周辺部位に多数の呼吸性ニューロンが分布している。第1の説では,延髄の網様体の呼吸性ニューロンが分布する範囲がこの機構の局在部位であると考え,第2の説では,延髄の背側部で呼吸性ニューロンのサブグループの一つである吸息性ニューロンが集まっている狭い領域(dorsal respiratory group,DRG)と,腹側部で上方に吸息性,下方に呼息性ニューロンが集合している限局した部位(ventral respiratory group,VRG)の両方を,この機構の所在部位と考える。最近,動物でDRGとVRGの局在部位を限局的に破壊したときの呼吸リズムの存否が研究され,両部位のニューロン群の機能が失われた後にも呼吸リズムが続くことが確認された。…
