Optimization of Professional Activity in Operators of Morning Chronotype Based on Bioelectrical Features of Brain

Abstract

Biorhythmological features and electroencephalography parameters in operators of morning chronotype demonstrate a significant mutual influence. In particular, frequency of the low-frequency beta-rhythm in left central leads and the total result of Ostberg-Stepanova test have an inverse correlation of average strength (rs = -0,697), which reflects the expressed ability of these operators to perform stereotypical, routine mental operations. In addition, total result of Ostberg – Stepanova test has a strong inverse correlation with frequency of low-frequency beta-rhythm in right central (rs = -0,704) and right temporal leads (rs = -0,738). This indicates that «pronounced larks» have the ability to quickly and efficiently perform repetitive mental operations, especially those associated with the impact of non-verbal auditory stimuli.
