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 subjectb) 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 andc) for each said sensor, quantifying a correlation that exists between said data indicative of sensory stimuli or of deliberate actions and the signals acquiredcharacterized 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.
