[The local blood flow and oxygen tension in the brain of pigeons under high-altitude hypoxia].
The effect of barochamber hypoxia on the local blood flow in the pigeon neostriatum caudalum, hypostriatum accessorium, ectostriatum, cerebellum cortex was studied by means of the hydrogen clearance technique. The hypoxia was shown to decrease the oxygen available in the brain tissue and to increase the blood flow. The changes were different in different brain structures. The spectral analysis of the oxygen available fluctuations revealed no regular changes in the temporal pattern of the fluctuations.
