[The effect of stimulation of the orbitofrontal cortex on the activity of the bulbar respiratory neurons and on respiration in normal rats and in hypoxia].
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.
