Before revision:  We observe that lineage distance between neurons , rather than the physical distance between their cell bodies, strongly influences the probability of a connection between them. In addition, the length of neuronal processes, as well as, their birth times determine connectivity. Together, these results help connect the physical location and morphology of neurons with the URLanization of the network.
After revision:  We observe that neurons with certain shared characteristics - such as, neural process lengths, birth time cohort, lineage and bilateral symmetry - exhibit a preference for connecting to each other. Recognizing the existence of such homophily helps in connecting the physical location and morphology of neurons with the URLanization of the network.
