The article presents the results of a study of the seasonal dynamics of speed and stability of simple visual-motor reactions (MCH) of the students enrolled in high school in the North, taking into account gender and ethnic dimensions. The survey, based on voluntary informed consent was attended by 110 women (70 Yakut and 40 Russian) and 85 men (50 Yakut and 35 Russian). The results showed the presence of significant differences in the speed and stability of MCH in men and women. Revealed that the excitation force, mobility and speed of conduction of excitation in nerve networks weaker in women than in men, regardless of ethnicity. Suggested that the seasonal dynamics of speed MCH students Yakuts associated with evolutionary develop a mechanism of adaptation to a pronounced seasonal photoperiodism in the North and is the basis for optimal viewing.
