Monitoring Evoked Potentials and Cerebral Circulatory Index in Acute Cerebrovascular Disorders and Posthypoxic Brain Damage: Localized Brain Function vs Whole Brain Circulation and Metabolism
Evoked potentials (EPs) such as auditory brainstem responses (ABRs) and somatosensory evoked potentials (SEPs) reflect localized brain function and have been widely used in the diagnosis of primary lesions in the central nervous system  On the other hand, the cerebral circulatory index (CCI), calculated as the reciprocal of the difference in oxygen content between arterial and cerebral venous blood (Fick’s principle), can be used as a clinical indicator to evaluate whole brain circulation and metabolism .
