Visual and auditory evoked potentials were recorded in 19 volunteers during their monotonous activity. Three groups of subjects different in performance quality were set aside. Characteristics of evoked potential components were subjected to analysis of variance. The latency of P1 component of visual and auditory evoked potentials recorded in respective projection cortical areas significantly increased over the course of the long-term monotonous activity. These changes were associated with performance deterioration. The observed changes in performance quality and brain functional state were determined by individual features of subjects.
