title: Long-term sleep deprivation as a game. The wear and tear of wakefulness.
abstract: We report here the first sleep deprivation study done on a group of 5 healthy students (1 female, 4 males, 23-24 years of age) while playing a game (Triviant). In 2 persons an EEG was recorded for 6 consecutive 24 h periods with an ambulatory monitor from the baseline night until 72 h after deprivation. The baseline night showed normal hypnograms. The students were deprived of sleep for 65 h following the baseline night. Sleep deprivation was complete and resulted in bradyphrenia, loss of memory and contact with reality, ataxia, decrease in body temperature and loss of body weight. The main sign of recuperation was a strongly increased slow-wave sleep synchronization during the first recuperation period (day-time sleep) only. There were no signs of REM rebound.
