 note = {The physiological functions (contingent negative variation (CNV), critical flicker fusion frequency (CFF), oral temperature. blood pressure and heart rate) of five subjects were measured every three hours in 36-hour sleep deprivation and twice after the recovery night. The subjects were given tasks (Uchida-Kraepelin test. etc.) and were made to fill out a self-rating questionnaire of subjective symptoms and the Stanford sleepiness scale (SSS) before every measurement. The CNV area decreased sharply at and after 3:00 of the second day, and dropped to its minimum at 9:00 of the same day and still did not increase after the recovery night. The number of subjective symptoms reached its maximum at 6:00 and 9:00 of the second day. A close correlation was found between the number of subjective symptoms and the CNV area during sleep deprivation. The SSS was at its maximum at 6:00 of the second day and a good correlation was found between the SSS and the CNV area. The correlation between the CNV area and CFF and between the CNV area and oral temperature was slight. The CNV is meaningful as an index which objectively indicates the drop in arousal level caused by sleep deprivation.},
