Abstract

Stimulation of the orbito-frontal cortex inhibited activity of bulbar expiratory, inspiratory and reticular (non-respiratory) neurons. The first phase of hypoxia generated facilitatory influence of cerebral activating structures, whereas the second phase led to a contrary effect (depression). Subcortical activating structures, however, retained some of their facilitatory influence thus maintaining the oxygen homeostasis of the organism.

摘要

眶额皮质的刺激抑制了延髓呼气、吸气和网状(非呼吸)神经元的活动。缺氧的第一阶段对大脑激活结构产生促进作用,而第二阶段则产生相反的作用(抑制)。然而,皮质下激活结构保留了一些促进作用,从而维持机体的氧稳态。
