Abstract

To evaluate the effects of sleep habits on the powers of beta waves and the sensory motor rhythm of the electroencephalogram (EEG), female college student subjects were divided into four groups, according to their sleep habits, as follows: GSHG (Good Sleep Habit Group), CSHG (Common Sleep Habit Group: late bedtime), CSDG (Cognitive Sleep Disorder-Delayed Sleep Phase Syndrome Group), and NSDG (Non-cognitive Sleep Disorder-Delayed Sleep Phase Syndrome Group). Brain function was stimulated by reading a book for 3 min in the morning (9~12 am) and the EEG was measured. According to the results, the powers of the beta waves and sensory motor rhythm were not different during the resting period among the four groups. However, during the reading stimulation period, the powers of beta waves and the sensory motor rhythm in the GSHG were significantly greater than in the other groups ($p$ <0.05). Beta powers during stimulation also increased in all brain areas in the GSHG ($p$ <0.05). Interestingly, these were decreased in the frontal and temporal lobes in the CSHG by the reading stimulation ($p$ <0.05). On the other hand, sensory motor rhythm, which represents focusing efficacy, only improved in the GSHG. These results indicate that the brain's focusing function during the reading stimulation was not properly operating in the morning in the female college students who had a delayed bedtime and bad sleep habits.

본 연구의 목적은 수면장애가 뇌파(EEG)의 beta파와 감각운동리듬(sensory motor rhythm)에 미치는 영향을 규명하는 것이다. 여자 대학생을 대상으로 하여 수면습관에 따라서 다음과 같이 네 군(n=6)으로 나누었다. 즉, 좋은 수면습관을 가진 GSHG (Good sleep habit group), 일반적으로 대학생들이 늦게 취침하는 수면 습관을 갖고 있기 때문에 오전 0~2시에 취침하는 CSHG (Common sleep habit group), 수면위상지연증후군으로 자신의 수면 장애를 인식하고 있는 CSDG (Cognitive sleep disorder with delayed sleep phase syndrome group), 수면장애를 인식하지 못하는 NSDG (Non-cognitive sleep disorder with delayed sleep phase syndrome group)으로 나누었다. 뇌파는 QEEG 8-System을 사용하여 오전 9~12시 사이에 측정하였다. 책읽기 자극시에 뇌파를 측정하여 안정시 기준치와 비교 분석하였다. 연구 결과, 책읽기 자극시 beta파와 감각운동리듬 상대파워는 GSHG가 다른 세군에 비하여 유의적으로 높았다($p$ <0.05). 책읽기 자극시 수치와 안정시 기준치를 대응 비교하여 볼 때에도, GSHG에서 beta 파워가 대뇌피질의 모든 부위에서 유의적으로 증가하였다($p$ <0.05). 그러나 CSHG에서는 전두부와 측두부에서 beta 파워가 감소하였다($p$ <0.05). 한편 CSDG와 NSDG에서는 책읽기 자극에 의하여 beta 파워의 유의적인 변화가 발생하지 않았다. 감각운동리듬 상대파워는 GSHG에서만 책읽기 자극에 의하여 향상되었다. 결론적으로 여자 대학생에게 있어서 오전 0~2시경에 늦게 취침을 하면 다음날 오전에 집중력 뇌파인 beta파 기능이 현저히 감소하고, 수면습관이 나쁘면 자신의 수면장애에 대한 자가인식 유무와 관련 없이 beta파와 운동감각리듬에 대한 뇌기능이 활성화되지 않아서 집중력에 부정적인 영향을 준다.
