摘要：The article explores neurodynamic characteristics and functional status of the central neural system according to the time parameters of sensory-motor reactions in native adolescent males of the Extreme North. The research involved 81 adolescent males: 42 Evenkis and 39 Koryaks aged 12—17 years studying at the boarding school in Evensk, Magadan Oblast. During the research reaction time for simple and complex sensory-motor reactions was measured. The article analyses quantitative criteria reflecting various aspects of CNS' functional status, such as: the functional level of the nervous system, persistence of reactions, the level of functional abilities of the developed functional system. The study revealed a significant improvement of these measures in subjects approaching 14—15 years (p < 0,05). In each age group of adolescent males there were subjects with low functional status of the CNS. Also, the ability to develop selective reactions was found low in 40 % of the subjects aged 12—15 years and in 18 % aged 16—17 years.
