Scientists at the University of Arizona researchers built a robot that's guided by a moth's brain impules.
The moth is immobilize inside a plastic tube mounted atop the 6-inch-tall wheeled robot. To get the moth to imitate flight, [professor Charles M.] Higgins and his team placed the moth in its apparatus on a circular platform surrounded by a 14-inch-high revolving wall painted with vertical stripes. The moth's neuron reacts to the movement of the stripes and the process begins.Link (Via ComDig)
The brain of a moth is about the size of a grain of rice. Although small, “its compact size and simplicity allows for an efficient way to do brain research,” Higgins said.
