Individual and Typological Characteristics of Operator's Eeg Reactions to Time Deviations in the Work/Rest Cycle

Abstract

The relationship between of individual typological characteristics and dynamics of the EEG rhythms was studied in human operators challenged by deviations in the work/rest cycle during 21-d isolation and confinement. Comparison of records made prior to and immediately after isolation showed that the relative power value (RPV) dynamics of the alpha-rhythm was dependent solely on parameters of the individual typological brain activity. Unlike RPV of delta, RPV of theta was unambiguously responsive to the experimental stresses, i.e. shift work in the conditions of 21-d isolation and confinement.
