English The circadian system consists of individual cellular clocks. It organizes and synchronizes biochemical and physiological processes in order to optimally adapt an organism to its environment. This requires that the circadian system is responsive to environmental cues, which contain information about geophysical time (e.g., light), and allows an organism to predict daily recurring events. However, the system needs to be responsive to unpredictable cues (e.g., predators, stress) as well, which makes it vulnerable in its task to synchronize body functions on a 24-h time scale. If unpredictable signals occur only occasionally, this will have a minor effect on the clock system. Conversely, stress signals that occur more frequently will desynchronize the various cellular and tissue clocks in the body. This will result in biochemical and physiological disorder and as a consequence will lead to various diseases including neurological and mood disorders.In this review, I will describe molecular mechanisms that have been associated with the circadian clock and mood-related behaviors.
