Tufts biologist Michael Levin peels open a rectangular Tupperware container to show off his babies: a dozen or so flatworms of the genus Planaria. They don’t look like much. Brown and about an inch long, they appear almost featureless as they swim around in spring water. But inside those little worms, says Levin, are surprisingly advanced brains. “They have most of the same neurotransmitters we do,” he says....And planaria have an ability we humans may never have—they can grow their brains back. “This is the only model species that enables the study of memory and brain regeneration in the same animal,” says Levin, a professor and director of the Tufts Center for Regenerative and Developmental Biology. His lab has been studying regeneration for years in animals.... [Keep reading HERE]
