Neurosciences: The Clock

University neuroscience researcher are uncovering how biological timing systems, like circadian clocks, control brain functions. This research provides insights about synchronization that can positively effect peoples health and well being. Why are heart attacks likely to strike before dawn, while asthmatic attacks generally occur after sunset? Why do we most often feel lethargic during short, dark days of winter, and more energetic in the long, sunny days of summer? The answer to each of these questions lies in understanding the role of the brain's clock in organizing our body functions around the external world, the daily cycle of darkness and light. Circadian clocks impose order on cells, tissues and organs, modulating body processes over the day-night cycle. This research has important applications: Malfunctioning of the brain's circadian clock results in disorders in brain and organ function, which cause disorders in sleep, brain degeneration and diseases like Alzheimer's and Parkinson's diseases. It is hoped that the research performed today may someday prevent diseases and provide strategies for minimizing sleep and cognitive disorders.
