Bioelectrical gradients guide embryonic development by creating an electrical scaffold for tissue and organ growth. Researchers harness the power of bioelectricity to devise strategies for regenerating various tissues, including promoting brain recovery after stroke. In this episode, Iris Kulbatski from The Scientist spoke with Paul George, a physician scientist in the Department of Neurology at Stanford University, to learn more about his team’s research on bioelectricity for stroke recovery. The Scientist Speaks is a podcast produced by The Scientist’s Creative Services Team. Our podcast is by scientists and for scientists. Once a month, we bring you the stories behind news-worthy molecular biology research.
