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