||P.309 6th paragraph: "The CSF space is a dynamic pressure system. CSF pressure determines intracranial pressure with physiological values ranging between 3 and 4 mmHg before the age of one year, and between 10 and 15 mmHg in adults." P.314 left column bottom paragraph: "Physiological values of CSF pressure vary according to individuals and study methods between 10 and 15 mmHg in adults and 3 and 4 mmHg in infants. Higher values correspond to intracranial hypertension. CSF pressure varies with the systolic pulse wave, respiratory cycle, abdominal pressure, jugular venous pressure, state of arousal, physical activity and posture."
