[Cerebrovascular response in newborns].
It was shown by the plethysmographic method that, in contrast to adult animals, in the newborn rats the blood vessels of the cerebral hemispheres and of diencephalon while displaying a distinct response to oxygen, failed to react to carbon dioxide, the latter being attributed to the low carbonic anhydrase activity in the tissues of these portions of the brain.
