Abstract: FIELD: medicine. 
     SUBSTANCE: group of inventions relates to medical equipment, specifically to a system and method for determining the state of stress based on an EEG signal and electrodermal activity. System includes a signal receiving unit, a primary signal processing unit, a filtered primary signal processing unit, a stress state determining unit and a data output unit. When the method is implemented, an EEG signal is obtained from the user's neurointerface through a signal reception unit. Electrodermal activity signal is obtained from a user's bracelet by means of a unit for receiving an electrodermal activity signal. Signal reception unit is connected to the signal primary processing unit. Signal primary signal processing unit is connected to filtration unit of primary processed signals. Primary signal processing unit is used to perform primary processing of the EEG signal by spectral decomposition of the derived EEG signal into cerebral rhythms and primary processing of the electrodermal activity signal. Using the filtration unit of the primary processed signals, signals are checked for noise and aggregation of the primary converted signals of left-hemispheric and right-hemispherical alpha rhythms is performed. State of stress is determined by determining the stress state correlate by means of the stress condition determination unit. Stress state determination unit is connected to filtration unit of primary processed signals and is configured to determine frontal asymmetry, averaging sum of leads along sliding window, determining the standard deviation of the stress indicator and the global average stress indicator, determining the state boundary and leaving it, assessing the level of the emotional response to electrodermal activity, and determining the absolute value of the stress indicator. Unit for outputting data is connected to the stress state unit. Data output unit output data by providing user with obtained results. 
     EFFECT: higher reliability of determining current state of stress due to higher accuracy of processing obtained data and expanded interpretation of data on brain activity of user in real time.
