The invention relates to a field of medicine and medical devices. An apparatus for registration of transitions between psychophysiological states of individual comprising a reading unit arranged to be capable of measuring an electromotive force under direct electric current of 0.5 to 5.0 microampere to produce a signal; at least two electrodes connected to reading unit, electrodes arranged to be capable of fixing upon the body of individual; a logarithmic unit, quantization unit comprising a comparator arranged to be capable of determining of whether the difference between the current and the previous signal value is greater than N, where N is a predefined value from 0.1 to 2.0 centineper; and a pulse generator arranged to be capable of generating a pulse having an amplitude of N when the difference between the current and the previous signal value is greater than N; the apparatus further comprising a compensating unit, a processing unit capable of monitoring the pulse values; and at least one power supply. A method for registration of psychophysiological state transition of individual comprises the following steps: (a) measuring of electromotive force between electrodes fixed upon the skin of individual under flow of direct current in interval from 0.5 to 5.0 microampere; (b) logarithming of signal; (c) quantizing the logarithm of signal from step (b) by level from 0.1 to 2.0 centineper; and (d) determining a transition between psychophysiological state of the individual either by registering sudden increase of unidirectional signal pulses amount, or by registering a shift in signal level up to 1.5-3.0 fold as compared to initial value. |
