Abstract: Method for locating a brain activity, including the following steps: a) applying to a subject a first series of sensory stimuli and acquiring, by a group of sensors, respective first series of signals representative of a brain activity associated with a first task effected or imagined by the subject in response to the sensory stimuli of the first series, each sensor being sensitive to the activity of a respective region of the brain of the subject; b) applying to the subject a second series of sensory stimuli and acquiring, by the group of sensors, respective second series of signals representative of a brain activity associated with a second task, different from the first task, effected or imagined by the subject in response to the sensory stimuli of the second series; and c) constructing, for each sensor, a multidimensional variable representative of the corresponding first and second series of signals, and determining a coefficient of correlation between the multidimensional variable and an observation vec

Abstract: Method for locating a brain activity, comprising the steps consisting in: a) acquiring data indicative of sensory stimuli addressed to, or deliberate actions performed or imagined by, a subject; b) by means of a plurality of sensors, acquiring signals representative of an activity, associated with said stimuli or deliberate actions, of respective regions of the brain of said subject; and c) for each said sensor, quantifying a correlation that exists between said data indicative of sensory stimuli or of deliberate actions and the signals acquired; characterized in that, for each said sensor, said correlation is established between a scalar variable indicative of a said sensory stimulus or of a said deliberate action and a multidimensional variable representative of signals that are associated therewith. Application of this method to the determination of optimum locations for brain activity sensors for direct neural control.
