Hippocampus and cortex in mouse brain. To trace the longer pathways that interconnect different brain regions, CBS labs developed a genetic method to label each individual nerve cell a different color to identify and track axons and dendrites over long distances. With light microscopy, scientists image the branching patterns and connections of all the axons within a region of the nervous system in transgenic mice that express a number of different fluorescent proteins in individual neurons. The idea here is to color-code the individual “wires” and “nodes.”
