• subsequently sensing said subsequent event related pattern of physiological activity generated in the brain with said sensor adapted to be operatively disposed with respect to the scalp or skin of said individual to provide signals representative of said subsequent event related pattern of physiological activity generated in the brain;
• subsequently transforming said signals representative of said subsequent event related pattern of physiological activity generated in the brain into subsequent pattern classification feature signals representative of said subsequent event related pattern of physiological activity generated in the brain of said individual in said data acquisition/transformation stage;

• comparing the stored said first pattern classification feature signals of said first event related pattern of physiological activity generated in the brain of said individual with said subsequent pattern classification feature signals representative of said subsequent event related pattern of physiological activity generated in the brain of said individual in said data acquisition/transformation stage to indicate the identification thereof, said first stimulating is the providing of a first series of stimulation events to evoke a first series of event related patterns of physiological activity generated in the brain, said first sensing by at least one sensor adapted to be operatively disposed with respect to the scalp or skin of said individual provides a first series of signals representative of said first series of first event related patterns of physiological activity generated in the brain, said first transforming is by said data acquisition/transformation stage that transforms said first series of signals representative of said first series of first event related patterns of physiological activity generated in the brain into first patterns classification feature signals representative of said first event related patterns of physiological activity generated in the brain of said individual and said providing memory is the storing of said first pattern classification feature signals of said individual.

A method of identifying a brain impaired condition of an identified individual based upon data representing at least one pattern of physiological activity generated in the brain of said individual comprising:

• a first stimulating of said individual with a first stimulation event which includes at least one stimulus to evoke a first event related pattern of physiological activity generated in the brain;
• a first sensing of signals representative of said first event related pattern of physiological activity generated in the brain with a sensor adapted to be operatively disposed with respect to the scalp or skin of said individual;
• a first receiving of said signals representative of said first event related pattern of physiological activity generated in the brain in a data acquisition/transformation stage;
• a first transforming of said signals representative of said first event related pattern of physiological activity generated in the brain into first pattern classification feature signals representative of said pattern of physiological activity generated in the brain of said individual in said data acquisition/transformation stage;
• providing memory in said data acquisition/transformation stage to store said first pattern classification feature signals of said first event related pattern of physiological activity generated in the brain of said individual;
• subsequently stimulating said individual with a subsequent stimulation event which includes at least one stimulus for said individual to evoke a subsequent event related pattern of physiological activity generated in the brain;
• subsequently sensing said subsequent event related pattern of said physiological activity generated in the brain with a sensor adapted to be operatively disposed with respect to the scalp or skin of said individual to provide signals representative of said subsequent event related pattern of physiological activity generated in the brain;
• subsequently transforming said signals representative of said subsequent event related pattern of physiological activity generated in the brain into subsequent pattern classification feature signals representative of said subsequent event related pattern of physiological activity generated in the brain of said individual in said data acquisition/transformation stage;
• and
• comparing the stored said first pattern classification feature signals of said first event related pattern of physiological activity generated in the brain of said individual with said subsequent pattern classification feature signals representative of said subsequent event related pattern of physiological activity generated in the brain of said individual in said data acquisition/transformation stage to indicate a brain impaired condition thereof, said first stimulating is the providing of a first series of stimulation events to evoke a first series of event related patterns of physiological activity generated in the brain, said first sensing by at least one sensor adapted to be operatively disposed with respect to the scalp or skin of said individual provides a first series of signals representative of said first series of first event related patterns of physiological activity generated in the brain, said first transforming is by said data acquisition/transformation stage that transforms said first series of signals representative of said first series of first event related patterns of physiological activity generated in the brain into first patterns classification feature signals representative of said first event related patterns of physiological activity generated in the brain of said individual and said providing memory is the storing of said first patterns classification feature signals of said individual.
