Researchers at the University of Freiburg recently turned to Star Trek to find answers about animal cognition and behavior. A holodeck system was constructed for flies, mice and fish, animals commonly used in neurobiology and behavior research. The goal was to separate movement from sensation, two processes that are linked in the brains of humans and animals. The 3D virtual environments included images such as vertical columns, plants, and even space invaders, and the animals' behavior in the environments provided answers that scientists have been unable to obtain through studying animals in non-virtual settings.
