説明

In the present study was investigated whether or not changes in spontaneous skin potential response (SPR) during sleep could be used as an indicator of psychophysiological activity. During the natural nocturnal sleep over 3 consecutive nights, 15 males entirely inexperienced in this type of experiment were observed with respect to the laboratory adaptation in terms of objective measures of EEG as well as of subjective measures using the rating-scale method and the questionnaire method. In addition changes in spontaneous SPR on the finger and on the dorsal hand were investigated during the adaptation process due to the laboratory effect. The following summary is based on the comparisons between the first and the third night results.<br>1. From the EEG profile, shortened latencies of sleep onset (stage 1), and of para-sleep, decreased relative duration of stage 1 and 2, and an increase duration of stage 4 were observed, and the findings confirmed the laboratory adaptation phenomenon (Table 1 & 2).<br>2. The subjective evaluation immediately after awakening revealed: i) disappearance of difficulty in falling asleep, ii) improvement in the feeling of a sound sleep and refreshed feeling after awakening, and iii) disappearance of the tendency of overestimating sleep latency. These results confirmed those in terms of the objective measures (Fig. 1 & 2).<br>3. The SPR frequency during allnight sleep decreased both on the finger and on the dorsal hand, and this decrease was more evident in the latter half of sleep (Fig. 3).<br>4. The SPR decreased in the stages of low amplitude EEG, i.e., stage 1, 2 and para-sleep, and no such decrease was observed in stage 4 (Fig. 4).<br>5. The correlation between the EEG stages and the SPR frequency on the finger and the dorsal hand was the lowest during the first night, but it increased later. The correlation between the EEG measure and the SPR frequency was higher when the latter was measured on the dorsal hand than when on the finger (Table 4).<br>6. Comparison of the changes of the SPR between finger and dorsal hand revealed a larger decrease for finger in stages 1, 2 and para-sleep which showed adaptation (Fig. 5).<br>7. The proportion of the period of para-sleep accompanied by SPR-bursts to the total para-sleep decreased (Fig. 6).<br>8. The spontaneous SPR during sleep has been explained as the release of cortical inhibitory center. However, the authors intended to revise this theory by proving the co-existence of psychophysiological mechanism, and the relationship between the activity of cortical inhibitory mechanism and that of the psychophysiological mechanism was discussed.
