Nighttime drop in body temperature: a physiological trigger for sleep onset?P J Murphy
Department of Psychiatry, Cornell University Medical College, White Plains, New York, USA
Sleep 20:505-11. 1997..It is suggested that a rapid decline in core body temperature increases the likelihood of sleep initiation and may facilitate an entry into the deeper stages of sleep...
Age differences in the spontaneous termination of sleepP J Murphy
Laboratory of Human Chronobiology, Department of Psychiatry, Weill Medical College of Cornell University, White Plains, NY 10605, USA
J Sleep Res 9:27-34. 2000..It is speculated that age-associated changes in sleep continuity may render unnecessary the putative role of REM sleep in providing a 'gate' to wakefulness...

Department of Psychiatry, Cornell Medical College, New York, USA
J Sleep Res 5:165-72. 1996..Performance improvements were significantly related only to sleep and not to circadian phase. The implications for non-circadian treatments of sleep maintenance insomnia and cognitive functioning in the elderly are discussed...

Department of Psychiatry, Cornell University Medical College, White Plains, New York, USA
Sleep 18:408-16. 1995..These findings suggest that middle-aged subjects may be less phase-tolerant than young subjects, and they raise questions concerning the utility of bright-light interventions in some shift-work populations...

Sleep 16:638-40. 1993..Nappers showed a tendency for shorter free-running periods in both variables, when compared with Nonnappers. These findings emphasize the need for careful reassessment of data obtained from traditional free-run protocols...
