Abstract

The article considers brain bioelectric activity in 250 healthy adolescents aged 14–17 years constantly living in subpolar (lat. 64°30’ N) and polar (lat. 67°40’ N) regions. We observed higher activity of subcortical diencephalic brain structures in adolescents living in polar regions, namely: raised levels of theta-activity and presence of photic driving response. Adolescents living in subpolar regions showed a more intensive optimization of neurodynamic processes.
