Method and/or system for personal identification and impairment assessment from brain activity patterns

摘要

The invention provides an apparatus and method for identifying individuals based upon patterns of physiological activity generated in the brain and for distinguishing between normal and impaired brain states in any particular individual. These patterns may be obtained by directly or indirectly recording the electrical and/or magnetic activity associated with sensory, cognitive, and motor processing in the brain. This activity may be recorded using sensors placed in, on, or near the scalp. In this system, samples of individual brain activity are stored in an "intelligent" data base of a data acquisition/transformation stage which has the capability to learn to distinguish the individual characteristics of normal patterns of brain activity.
