Recording and Analysis of Circadian Rhythms in Running-wheel Activity in Rodents
Published on: January 24, 2013
Objective:
Circadian rhythms describe the near 24-hour oscillations observed across almost all biological processes on Earth. These rhythms serve to coordinate our behavior and physiology with the 24-hour light-dark environment in which we live. This article highlights normal circadian physiology and the disorders that can develop when those processes are disrupted.
Latest Developments:
Although historically circadian dysfunction has been viewed in terms of sleep-wake disorders, there is growing recognition that circadian disruption can contribute to or result from many other disorders frequently encountered within neurology.
Essential Points:
When caring for patients, it is important to recognize time as a variable in disease presentation and as a potential treatment that can be harnessed to optimize patient outcomes.
