Einstein Image

To turn r-a-t into a-r-t, colorize its paths to a lever (at top) that releases a shot of sugar water. Morphing a graph into rainbow-tinged strings was the idea of addiction researcher Saleem M. Nicola, Ph.D. In this study, he and colleagues trained rats to press the sugar-releasing lever after hearing a tone, and the colors represent one animal’s orientation on hearing the tone multiple times: warmer colors indicate that the rat is facing away, while cooler tones show that it has turned toward the sugar. The image was a winner of the Federation of American Societies of Biology’s BioArt competition. Dr. Nicola is an associate professor in the department of psychiatry and behavioral sciences and in the Dominick P. Purpura Department of Neuroscience.
