Patent ID: 8731650

Claim:
A method for interpreting brain activity monitored by an array of brain activity sensors applied to the head of a subject, wherein each of the sensors are adapted to generate a response signal upon prompting of the subject by an external stimulus, comprising: receiving two or more response signals from the array of brain activity sensors, each response signal corresponding to a different brain activity sensors; determining two or more spatial weighting coefficients, each corresponding to one of the two or more response signals; weighting each of the two or more received response signals in accordance with a corresponding one of the determined weighting coefficients; and generating an output from the weighted two or more response signals, the output having a correlation to the brain activity of the subject in response to the external stimulus, wherein the determining of two or more weighting coefficients comprises determining two or more weighting coefficients such that the weighted responses are maximally discriminating between first and second predetermined times corresponding to two stimuli where a maximum difference in brain activity is expected.
