The proposal relates to the field of physiology and designed to optimize the brain and electroneurostimulation cerebral subcortical nuclei of the central nervous system and the cranial nerves. The device comprises a matrix of stimulation maxillary modular electrode assembly, which is manufactured individually by modeling the impression of the upper jaw fixed to the teeth, which is placed working units of the device, consisting of a miniature control unit connected with the gyro and having a number of special programs for electrostimulation implemented individually for each patient miniature power supply unit built in the maxillary module, set of a plurality of external electrodes installed on the edge of the module, and electrodes included in the electrode stimulus array having a number of corresponding outputs, distributed along the latter in such area as to stimulate oral surface through individual electrodes respectively, used programs, activated in accordance with the gyro body registrable deviation from the vertical, that is certain Oblas ti oral cavity corresponding to the individual cranial nerves, the use of the device allows for conductive and trophic stimulation of the nervous system, communication with the central nervous system organs innervated, and stimulation optimization activity control systems of the body, maintaining its active life, the prevention of various diseases.
