By mashing up brains from various insect species, neuroscientists at the University of Arizona introduce a practical technique for quantifying the neurons that make up the brains of invertebrate animals. In addition to revealing interesting insights into the evolution of insect brains, the work provides a more meaningful metric than traditional studies measuring brain size or weight.
