Abstract

The purpose of our work is the determination of the most significant indicators of bioelectic activity of the brain based on the results of electroencephalography (EEG) in persons who get acoustic trauma in the zone of realization of military operations, taking into account the degree of violations of the auditory function. A group of servicemen with acoustic trauma (205 people) was examined with the most typical forms of audiometric curves - with a downward, often - ubrupt type of the curve, who were divided into three groups, depending on the severity of sensorineural hearing loss. The research was carried out using the computer electroencephalograph of the firm “DX-System” (Ukraine) according to the generally accepted method according to the scheme of electrode overlaying “10-20”. It has been shown that changes in the bioelectric activity of the brain in patients with acoustic trauma have been characterized by deformation of the dominant rhythm with poor modulation and weakening of the response to functional loads, especially in the frontal and temporal directions. They significantly decreased the percentage content of the α-rhythm dominant in the normal EEG picture and increased the representation of the β- and Δ-rhythm, both in the background recording and in the case of functional photo stimulation and hyperventilation. The most significant changes in bioelectrical activity compared with the control group were observed in persons of the 2nd (more severe hearing impairment) and 3rd (with severe violations of the auditory function) groups. For example, in the 3rd group in the background, the Δ-rhythm content in the frontal leads increased to 19,74±1,53 % relative to 8,5 ± 1,6 % in the control group. The comparative analysis of the percentage of EEG rhythms conducted between the groups under study shows that from 1 to 3, the representation of the Δ, θ and β-rhythm increases, and the α-rhythm particles decrease as with the background record, so and with functional on-loadings. In the 3rd group, in the frontal leads, a significant difference was observed in the percentage values of all of the major EEG rhythms under study (α, β, θ, Δ), both in the background recording and in functional loadings. For example, the percentage of Δ-rhythm in the frontal leads with a background note was 19,47 ± 1,53 %, which significantly differs from the indicators of the 1st – 13,69 ± 0,68 % and the 2nd group – 13,04 ± 0,52 %. Thus, persons with combat acoustic trauma revealed a violation of the bioelectric activity of the brain. Together with a decrease of auditory function there is a redistribution of the basic rhythms of the EEG in the direction of increasing the manifestations of slow-wave activity on the disorganized background, especially in the frontal and temporal directions.

Keywords: auditory analyzer, acoustic trauma, central nervous system, bioelectrical activity of the brain.
