Twenty-four hours a day, seven days a week, participants in studies conducted by the hospital's Laboratory for Circadian and Sleep Disorders Medicine are busy contributing to the study of circadian rhythms, the science dealing with the operation of one's "biological clock...
...high school, Heller worked at a neuroscience lab that researched circadian rhythms. Heller developed a software program that enabled researchers to screen out "noise" from their data, isolating particular signals and thus giving them better results. While there are now commercial programs that do this, Heller's work was then so extraordinary that he was asked to present it at a meeting of the International Society for Neuroscience during his senior year...
...study is being conducted by the Center for Circadian Medicine at the Brigham and Women's Hospital. Participation involves a week of home monitoring, then living in our lab, free from time cues, for up to 15 days (and nights). We monitor your temperature, EEG and hormone patterns. Those completing the study will earn $700 to $1,000. If interested call...
...best-known rhythms are circadian, from the Latin, meaning "about a day." The sleep-wake cycle is the most obvious, but the body's production of hormones also fluctuates significantly over 24 hours. Says Charles Ehret, president of General Chronobionics, a research and consulting company in Hinsdale, Ill.: "Chemically, you are a very different person at noon than you are at night...
Although only one subject was involved in this study, the project did provide new evidence of what affects a person's circadian pacemaker, the part of the brain that sets the biological clock, coordinating hormone and chemical changes with the external environment, according to Charles A. Czeisler, the study's primary investigator and an assistant professor of biology...
