As time glows by: Watching circadian clocks in the brain
Dr. Erik Herzog
Department of Biology, Washington University in St. Louis
Abstract: What wakes us up? Our daily schedules are set by a biological clock with a near 24-hour period. This circadian clock must synchronize our physiology and behavior to local time. When we travel across time zones, work shifts, or adjust to Daylight Saving Time, the circadian cells in our brain and body must adjust to the new schedule. Using reporter genes and multi-electrode arrays, we can now watch circadian clocks keeping time in real time. This talk will discuss the molecules, cells and circuits underlying daily rhythms in physiology and behavior, their relevance to human health, and what happens when we try to defy our circadian clock.
