Value We used the following juices, listed in roughly decreasing order of preference (associated colors in parenthesis): high-sugar lemon Kool-Aid (dark yellow), grape juice (bright green), fruit punch (magenta), apple juice (diluted to 1/2 with water, dark green), cranberry juice (diluted to 1/3 or 1/4 with water, pink), water (white), milk (red), peppermint tea (bright blue), tea (light brown...
AIM OF THE STUDY To explore the effects of caffeine and bright light therapy on simulated nighttime driving in sleep-deprived healthy volunteers. PARTICIPANTS AND METHODS Twelve male healthy volunteers aged 20 to 50 years participated in a randomized cross-over study of simulated nighttime driving at a sleep laboratory, followed by recovery sleep with polysomnography at home. The volunteers r...
Exposure to light at night increases alertness, but light at night (especially short-wavelength light) also disrupts nocturnal physiology. Such disruption is thought to underlie medical problems for which shiftworkers have increased risk. In 33 male subjects we investigated whether short-wavelength attenuated polychromatic white light (<530 nm filtered out) at night preserves dim light melatoni...
Stress, or threats to homeostasis, is a universal part of life. Organisms face changing and challenging situations everyday, and the ability to respond to such stress is essential for survival. When subjected to acute stress, the body responds molecularly and behaviorally in order to recover a steady state. We developed a simple and robust assay of behavioral plasticity for Drosophila larvae in...
