Correlation between brain blood flow and catecholamine levels in rat brain areas under hypobaric hypoxia.
Hypobaric hypoxia induces an important increase in the cerebral blood flow in all areas and more particularly in the bulb and hypothalamus; the increase in the cerebral blood flow allows for an oxygen intake sufficient to maintain the norepinephrine level in these structures.
