Abstract:
1. A system for monitoring a state of a brain, the system comprising: at least one internal electrode constructed and arranged to be placed adjacent to at least a portion of the brain and in communication with a system handler to provide a measurement thereto of electrical properties of the brain; the internal electrode being provided on an intracranial catheter that is constructed and arranged to be placed within the brain to monitor a condition of the brain as a measurement of electrical properties thereof; an intracranial pressure sensor for monitoring intracranial pressure within the brain by providing a measurement of pressure of the brain; and at least one exterior electrode placed proximate and exterior to the at least one internal electrode to generate a signal therebetween in order to return a state of blood flow-induced electrical properties of the brain, such that the electrical properties of the brain indicate the blood flow-induced status of the brain; wherein the status of the brain is determine by performing a group delay or phase shift analysis between the measurement of pressure of the brain and the state of blood flow-induced electrical properties of the brain.
