Table 1. Pairwise comparison of the alpha activity frequency characteristics (Hz) in occipital and parietal areas in the relaxed wakefulness state in the sitting position (observation № 1) and in the relaxed wakefulness state when lying down before falling asleep (observation № 2) (Student's t-test, KS-test norm < 0.01)

Pairwise comparison of the alpha activity frequency characteristics (Hz) in occipital and parietal areas in the relaxed wakefulness state in the sitting position (observation № 1) and in the relaxed wakefulness state when lying down before falling asleep (observation № 2) in individuals under the age of 30 years (Student's t-test, KS-test norm < 0.01)
