Patent ID: 8532756

Claim:
A computer-implemented method executed in an electronic data processing system having a computer program stored on computer readable media, the computer program for analyzing complex signals, the computer-implemented method comprising: obtaining, at the electronic data processing system, a first electronic signal representative of a first recorded brain signal of a living subject, the first electronic signal having a plurality of brain signal features, the first recorded brain signal having been recorded during a null condition when the living subject is not performing a task or receiving stimuli and is not in the midst of an epileptic event; calculating, by the electronic data processing system and using the first electronic signal, a brain signal features baseline comprising a statistical distribution description for each brain signal feature, the brain signal features baseline modeling, for the null condition, a likelihood of fluctuation of each brain signal from a baseline value in the null condition; obtaining, at the electronic data processing system, a second electronic signal representative of a second recorded brain signal of the living subject, the second electronic signal having a plurality of brain signal features, the second recorded brain signal having been recorded during a non-null condition of the living subject having been asked to perform a task or in the process of performing a task or the living subject receiving a form of stimuli; and comparing, by the electronic data processing system, the brain signal features of the second recorded brain signal with the brain signal features baseline to detect statistical deviations representative of an event comprising an occurrence of functional activity of the living subject, the functional activity associated with the performance of the task or the reception of stimuli.
