Abstract: The utility model relates to a device for non-invasive electrical stimulation of the endorphinergic center of the human and animal brain and finds application in the field of human and veterinary medicine. The device consists of a power supply unit which is connected on the one side to a low voltage power supply unit, on the other side to a control circuit board and an external communication unit. The low voltage power supply unit is connected via a main board to a main processor to which is connected a quartz resonator . The main processor is connected via a digital-to-analog converter and an analog-to-digital converter to a current generator with leads to electrodes. The control board comprises a processor which is connected to the main processor via an optron, which is connected to the current generator, a touch-screen display and an external communication unit via a second optron. The device, by means of an external communication unit has remote access for control and communication via the Internet, mobile operator or other type of wired or wireless communication. The device uses an electric current, with different characteristics in the frequency range from 60 Hz to 90 Hz, for different stimulations with quasi-resonant frequencies with options for variations. The electric current, which has monopolar rectangular current pulses, is applied to the electrodes to the front electrode with a positive potential, and to the electrodes of the mastoids - negative. The electric current can have bipolar rectangular current pulses, as the polarity of the front electrode and the electrodes of the mastoids is constantly changing, whereby each subsequent pulse has a different polarity. The electric current can be in the form of monopolar rectangular current pulses and at the same time with a constant electric current, as from the beginning to the end of the session a positive potential is applied to the electrodes and a negative potential to the electrodes of the mastoids as one type of the electric current is pulsed and the other is constant. The electrical stimulations described above are capable of both a fixed frequency with an accuracy of 0.01 Hz and a frequency variation in the range of ± 2.5 Hz around a fixed frequency. This allows stimulation in the entire quasi-resonance range, and the stimulation spectrum in the frequency range from 60 Hz to 90 Hz covers the quasi-resonant frequencies of humans and animals, providing highly effective stimulation with minimal stimulus pulse values. The electric current can be a direct electric current, without frequency variation, as from the beginning to the end of the session a positive potential is applied to the electrodes of the front electrode, and to the electrodes of the mastoids - negative, or vice versa, allowing via electrophoresis the entry of local anaesthetics or other medications through the skin. . Electric current is applied from 0 mA to 5 mA and the duration of the session is from 5 min to 60 min.
