FIELD: medicine.
SUBSTANCE: invention relates to medicine. Device contains successively connected sensor, device for registration of brain electric activity, delay lines, amplifiers with regulated coefficients of amplification, adders, unit for analysis of induced potentials, unit for controlling device of sending impact signal to subject, device of sending to subject short-lasting external signal of specified value, whose maximal value is smaller than value of signal, corresponding to pain syndrome, phase detectors. Device also contains unit of preliminary correction of central frequency of filtration band, which in addition contains switching unit, smoothing filter and threshold device.
EFFECT: invention makes it possible to increase accuracy of diagnostics of induced brain potential.
