title: [Reticular activity and intracranial pressure. Acute and chronic intracranial hypertension (author's transl)].
abstract: Modifications of mesencephalic and bulbar reticular formation activity were studied with microelectrodes during acute and chronic intracranial hypertension. In both cases, the mesencephalic reticular activity increased progressively until a pressure level of 70 to 90 cm of CSF was reached and then fell irreversibly to less than the base value. The bulbar reticular activity followed the same pattern but more slowly. Different hypotheses are advanced to explain these modifications and their meanings.
