[Changes in the functional state of the nervous system of students during studies]

The paper describes the function of the autonomic nervous system of students during their study at a higher educational establishment. There are changes in the activity of the sympathetic and parasympathetic nervous system during a study day and examination session. Findings indicate that the examination session is a strong stress to the students, which appears as significant rises in the higher tension index and in the Kerdo autonomic index and a reduction in the standard deviation of cardiac intervals.
