FIELD: medicine.
SUBSTANCE: electroencephalogram (EEG) is registered. Photostimulation is realised by alternation of two signals of different frequency. In EEG recording trace of second signal is detected in form of presence of signal, which is similar to second signal by its frequency-time parameters during re-stimulation of brain by first signal. If time of appearance of second signal trace after beginning of stimulation by first signal does not exceed 800 mc, norm is diagnosed, if it is higher than 800 mc, impairment of functional state of brain is diagnosed.
EFFECT: method makes it possible to increase self-descriptiveness and objectivity of CNS diagnostics, which is achieved due to provision of possibility of simultaneous determination of rate of processing, memorising and reproduction of external information independently on the level of tested person's consciousness.
