Ravi Allada raises the question why humans sleep. He talks about what happens when humans stay awake longer and how their performance declines with less sleep over time. He also talks about the circadian process.

Ravi Allada, MD, is the Professor and Chair of the Department of Neurobiology, Professor in the Department of Pathology, and Associate Director for the Center for Sleep and Circadian Biology at Northwestern University. Dr. Allada received his medical degree from the University of Michigan and completed his residency in clinical pathology from Brigham and Women's Hospital. During medical school, he was a Howard Hughes Medical Institute-National Institutes of Health Research Scholar and worked on the molecular genetics of general anesthesia using the fruit fly Drosophila as a model system. He received an HHMI Physician Postdoctoral Fellowship with Michael Rosbash at Brandeis University where he cloned the Drosophila Clock gene, a master transcription factor for circadian (~24 hour) clocks. In 2000, he joined the faculty at Northwestern University. His laboratory has identified and characterized novel components of the core circadian clock.
