Researchers have for the first time been able to identify neuronal correlates of behavior by comparing maps of synaptic connectivity, or "connectomes," between two species with different behavior. They compared the pharyngeal nervous systems of two nematodes, the bacterial feeding Caenorhabditis elegans and the predator/omnivore Pristionchus pacificus and found large differences in how the neurons are "wired" together.
