The article is devoted to the pecularities of inter- and intrahemigpheric relations at the early stages of evoked potentials changes in the stress situation, caused by the threat of the punishment during intellectual activity with time deficit. EEG, skin galvanic reaction and ECG were registrated; biochemical analysis of catecholamine Concentration in saliva was carried out. The component analyses of evoked potentials showed changes in occipital and frontal areas, as taking into account amplitude and latency changes of P150, N200 and N400 (increasing differences) and P300 (decreasing differences).
