Episode 2: Prosthetic Arms, Frozen Frogs and Alligator Hearts

In this episode of Life Lines, we speak with Todd Kuiken, a doctor at the Rehabilitation Institute of Chicago and a professor at Northwestern University, about his efforts to develop a prosthetic arm that responds directly to signals from the brain. He will describe his latest research, which appears in the Journal of Neurophysiology, published by the American Physiological Society. This segment begins at 1:41.In our 'Ask a Physiologist' section, we'll talk to Ken Storey of Carleton University in Ottawa, Canada, who will answer the question 'Can an animal freeze, then thaw out and live?' This segment begins at 9:23.In our final segment, APS Executive Director Martin Frank will talk to Jim Hicks of the University of California at Irvine about the uniquely structured alligator heart and the role it plays in digestion.
