The method comprises applying individual stimuli to different regions of a brain by means of the application of specific stimulus signals to corresponding stimulation elements arranged adjacent to said regions of said brain. The method comprises constructing one or more simplified models of the brain, or of one or more sectors of the brain, considering the brain or said sector thereof, as appropriate, as a non-linear coupled oscillating system, and comprises determining said stimulus signals so that the latter are suitable for exciting one or more natural vibration modes of said non-linear coupled oscillating system. The system comprises stimulation elements (E1, E2...En) arranged adjacent to regions of a brain, and an electronic system in connection with the stimulation elements (E1, E2...En) and intended for applying thereto corresponding stimulus signals and for determining same by applying the proposed method.
