Abstract

Compression of helium-oxygen mixture (HOM) and neon-oxygen one (NOM) led to changes in the guinea pig black substance, caudate nucleus and occipital cortex concerning the pO2. The pO2 level increased along with the increase in the HOM density to 15.56 milligrams and NOM to 76.61 milligrams. The pO2 changes were unequal in the cortex and deep structures of the brain. The increase in oxygenation of the brain under these conditions seems to occur because of compensatory responses of the cardiorespiratory system and redistribution of cerebral blood flow.
