Planarian flatworms swim in a petri dish in one of Michael Levin's labs in Tufts University's Center for Regenerative and Developmental Biology in Medford, Massachusetts, USA. The worms' movements are recorded (note: red dots on diagrams) in a computer-controlled automated learning and testing chamber which allows the training of flatworms in a controlled environment. Levin's research focuses on morphological and behavioral information processing in living systems. Some of the lab's recent experiments have looked at memory in flatworms using this device. A speck of food is placed in one quadrant of a petri dish and that quadrant is illuminated by a blue light. The flatworms seek out that food and retain that memory in subsequent tests even after regenerating most of their bodies.
