Changes in brain bioelectric activity at trained tunnel workers

Workers (men) at Severomuyskiy tunnel – 31 workers aged from 24 till 55 years are surveyed. The middle age was 42,5±1,6 years, middle age of training – 11,8±1,1 years. In group of tunnel workers contacting to a complex of adverse factors, were registered: expressed in 19,3±3,2%, moderate – in 64,5±6,5% and light in 16,2±2,9% cases the diffusion changes in EEG. For trained tunnel workers low-amplitude EEG with moderated and expressed diffusion changes in a type of irregularity α-rythm, strengthenings of expressiveness of slow and wave activity, mainly δ-range, existence of pathological center of various localization and signs of stem structures interest is characteristic.
