Patent attributes
The invention relates to a device and a method for transcranial, non-invasive, electrical deep-brain stimulation, of the kind used in particular in the treatment of neurological and psychiatric disorders and of disturbances of the motor/cognitive functions in the human brain, wherein the device has at least one signal generator for generating an electrical alternating-current signal, an electrode arrangement, which can be placed on the head of a person to be treated and can be connected electrically to the signal generator so as to apply an alternating-current signal, wherein the electrode arrangement can be used to apply at least two alternating-current signals, of which the trajectories cross the region of the brain to be treated, such that their alternating currents are superposed, as a result of which the region of the brain to be treated is stimulated by electrical alternating currents in a targeted manner, whereas adjacent regions of the brain are stimulated only slightly or not at all.
