TL;DR: The hypothesis that living in contemporary society produces a state of chronic sleep deprivation in humans is suggested.
Abstract: The sleep of 16 young adult male subjects was studied for 4 consecutive nights in the laboratory using all night electroencephalography. For the first 3 nights, the subjects retired for sleep at 11:00 p.m. and were aroused in the morning at 7:00 a.m. On the 4th night, the subjects retired at 11:00 p.m. and were allowed to sleep in the morning until they awakened spontaneously. The ad-lib sleep night resulted in 126 min more sleep than was found on the 3rd night of controlled sleep. These results suggest the hypothesis that living in contemporary society produces a state of chronic sleep deprivation in humans.

TL;DR: There was an increase in the amount of deep sleep (stage 4) during this period of sleep and on a recovery night, the first 6 hours revealed a significant increase in deep sleep and beyond this period there was a sharp increase in stage 1-rapid eye movement sleep.
Abstract: Eight young male subjects were permitted to sleep only 3 hours out of each 24 for 8 days. Electroencephalographic recordings were made during the 3-hour period of sleep. There was an increase in the amount of deep sleep (stage 4) during this period. On a recovery night, the first 6 hours revealed a significant increase in deep sleep, and beyond this period there was a sharp increase in stage 1-rapid eye movement sleep.

TL;DR: The interrelationships among slow-wave, spindle, and ripple events are defined, indicating that sleep disturbances may be associated with state-dependent decoupling of hippocampal and cortical circuits in psychiatric diseases.

TL;DR: RBD is rare, but REM sleep without atonia is relatively fre-quent in patients with probable Alzheimer disease, a tauopathy.
Abstract: Study objective To determine the frequency of rapid eye movement (REM) sleep behavior disorder (RBD) and REM sleep without atonia among patients with Alzheimer disease and control subjects. Design Overnight polysomnography. Settings Sleep laboratory. Patients Fifteen patients with probable Alzheimer disease (mean age +/-SD, 70.2+/-5.6) and 15 age-matched healthy control subjects (mean age +/- SD, 67.9 +/-5.4). Intervention N/A. Results Four patients with Alzheimer disease presented REM sleep with-out atonia. One of these patients had all the polysomnographic features of RBD, including behavioral manifestations during REM sleep. Conclusion RBD is rare, but REM sleep without atonia is relatively fre-quent in patients with probable Alzheimer disease, a tauopathy.
