The circadian clock and behavior.
Temporal organization is a fundamental feature of all living systems. Timing is essential for development, growth and differentiation and in the mature organism, it is essential to maintain normal physiology and behavior. The biological entity that permits an organism's day/night organization is the circadian system. In the following, we describe how daily or circadian activity is measured in mice, and what such activity measurements can tell us about the state of the animal.
