Sleep Performance Laboratory

Slide Notes
Studies in laboratories of sleep-deprived healthy adults have taught us much about the critical need for nightly sleep, the consequences for health and behavior of not obtaining adequate sleep, and the biological processes involved in sleep. The functions of sleep also have become increasingly clear. Healthy nightly sleep of adequate duration produces renewed alertness, enhances our ability to pay attention, consolidates our memories from the day before, improves our moods and relieves our fatigue, in addition to other biologically-mediated effects on brain and body. When sleep is disturbed or of inadequate duration, all of these functions show deficits.

And then the volunteers live on different sleep schedules in this environment, monitored 24 hours a day by both people, staff, but also by infrared cameras and monitoring systems. In the upper right of this slide, you see the computer test batteries that are used, that they work on every couple of hours to evaluate how their brain function and their behavioral performance and then in the laboratory you’ll also see other equipment for recording the physiology. The equipment that they wear is roughly a ten to fifteen thousand dollar unit that records all of this as they move around. This is the best way to identify and establish unequivocally that humans are being controlled by their need for sleep and their biological clock.
