Here's a neuron changing colors as its electrical activity changes. The bottom white trace simultaneously shows the cell's changes in electricity. The neuron contains a new protein called ArcLight A242 which can accurately sense subtle changes in voltage. Scientists spent many years developing this type of protein. It may greatly help researchers decipher nerve cell codes that underlie behavior. Courtesy of Dr. Vincent A. Pieribone lab, The John B.
