ABSTRACT. Under conditions of chemical pollution of the environment, the balance between chemical elements (CE), which play an important role in the course of neural processes, is changed. To determine the significance of 28 CE for the basic rhythm of the electroencephalogram (EEG), 119 urban adolescents 12-14 years old were examined. CE was determined in hair samples by X-ray fluorescent spectorophotometry. EEG in 10 leads was recorded with three functional states. Based on the results of correlation analysis, neurotropic effect of CE was determined taking into account the strength and significance of correlations between CE content and the spectral power of alpha rhythm. The "neurotropic” effect of CE was more expressed for toxic heavy metals at their content within the conditional norm, while the deficient content of essential CE was significant mainly in the eye-opening test.
