Device for measurement and analysis of brain activity of both cerebral hemispheres in a patient

摘要

The invention relates to a method and device for measuring cerebral electrical activity in a patient. Cerebral electrical activity is measured in the form of electrical signals. Said signals are amplified and converted to signals which are then stored. The digitized signals and/or the stored digitized signals are processed as individual signals and as two channel signals for both cerebral hemispheres of the patient. A brain function index is thus determined to measure the normality of the patient's brain function.
