以往曾报道小脑共济失调几例患者主诉有呼吸困难和呼吸道感染,证明最大呼吸容量明显降低。后以猫证明,小脑兴奋可通过两条途径影响膈运动神经原:①对呼吸活动起抑制作用;②对肋间一膈反射起促进作用,并超过或消除呼吸时相后朝肋间一膈反射引起的抑制作用。本文在于确定小脑损伤是否可以引 In the past there have been reports of cerebellar ataxia in a few patients complained of dyspnea and respiratory tract infections, demonstrated that the maximum respiratory capacity was significantly reduced. After the cat to prove that cerebellum excitability can affect the diaphragm motor neurons in two ways: ① on respiratory activity from inhibition; ② on the intercostal diaphragmatic reflex play a role in promoting, and to overcome or eliminate the respiratory phase toward the intercostal diaphragma Reflex-induced inhibition. This article is to determine whether the cerebellar injury can be cited
