title: Effect of carbon dioxide inhalation on the pattern of gaseous metabolism in ischaemic zones of the primate cortex. An experimental study of the 'intracerebral steal' phenomenon in baboons.
abstract: The cortical circulation of the baboon has been studied during ischaemia produced by middle cerebral occlusion. Evidence of reactive hyperaemia did not occur in hypercapnia. Metabolic studies as a whole present evidence of increased interference with gaseous metabolism during hypercarbic occlusion, despite raised venous pO(2) during hypercarbia. The significance of these findings is discussed.
