Abstract
A method and apparatus for assessment of hemodynamic and functional state of the brain is disclosed. In one embodiment, the method and apparatus includes non-invasive measurement of intracranial pressure, assessment of the brain's electrical activity, and measurement of cerebral blood flow. In some embodiments, the method and apparatus include measuring the volume change in the intracranial vessels with a near-infrared spectroscopy or other optical method, measuring the volume change in the intracranial vessels with rheoencephalography or other electrical method, and measuring the brain's electrical activity using electroencephalography.
