Join Fred Turek, PhD, from the Department of Neurobiology and Physiology at Northwestern University presents “The Role of the Circadian Cycle in Obesity and Metabolic Dysfunction,” the third in the new Basics of Sleep Webinar series. During this 60-minute session Dr. Turek discusses the interactions between sleep and metabolism, and the hypothesis that sleep disturbance is responsible for the "interacting epidemics" of sleep loss and obesity. He reviews our understanding of the basic mechanisms of circadian rhythms from behavioral expression to clock genes, and discusses how circadian dysregulation may underlie mental and physical disorders. He focuses on the role of circadian rhythms in control of metabolism. Dr. Turek has a long and distinguished history of contributions to the field and brings a broad perspective to this discussion. His work in the area of sleep and metabolism has ranged from animal studies of sleep restriction and the impact of disrupting the circadian clock, to speculation on the causes of mental illness, the metabolic syndrome and nocturnal eating syndrome.
