摘要：
The invention relates to a field of medicine and medical devices. An apparatus for registration of transitions be¬tween 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 com¬parator 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 generat¬ing 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 pow¬er supply. A method for registration of psychophysiological state transition of individual comprises the following steps: (a) mea¬suring 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 cen¬tineper 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.
