Abstract
Abstract A method analyzing event-related potentials (ERP), and their respective P300 brain wave responses of a subject to a repeatedly presented stimulus interspersed with non-significant stimuli. The method comprises providing a source of stimulation to the subject including personal knowledge and non-significant stimuli, detecting event related potentials of the subject, translating these potentials to P300 brain waves, and analyzing the P300 brain wave activity for personal knowledge detection. A computer is is utilized to interpret and analyze the responses for personal knowledge.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
105 words
A method of determining the cognitive response to personally meaningful information of a subject to a repeatedly presented significant personal knowledge stimulus or stimuli interspersed with nonsignificant stimuli comprising: (a) formulating a series of stimuli to be presented to the subject, said stimuli to include non-significant stimuli and possibly personally significant stimuli; (b) providing a source of stimulation to the subject, including said personal knowledge and said nonsignificant stimuli; (c) providing detection means for detecting event related potentials; (d) translating event related potentials to P300 brain waves; (e) obtaining P300 brain wave activity; and (f) analyzing said P300 brain wave activity for personal knowledge detection.
Claim 2
Independent Claim
105 words
A method of determining the cognitive response to personally meaningful information of a subject to a repeatedly presented significant personal knowledge stimulus or stimuli interspersed with nonsignificant stimuli comprising: (a) formulating a series of stimuli to be presented to the subject, said stimuli to include non-significant stimuli and possibly personally significant stimuli; (b) providing a source of stimulation to the subject, including said personal knowledge and said nonsignificant stimuli; (c) providing detection means for detecting event related potentials; (d) translating event related potentials to P300 brain waves; (e) obtaining P300 brain wave activity; and (f) analyzing said P300 brain wave activity for personal knowledge detection.
Claim 3
Dependent Claim
20 words
The method of claim 1 wherein the stimuli is at least one of a visual stimulus and an auditory stimulus.
Claim 4
Dependent Claim
25 words
The method of claim 1 wherein the step of providing a source of stimulation to the patient is further characterized as providing a speech-type stimulus.
