the positioning of kenyon cells depends on their birth order. the somata of early-born kenyon cells are pushed outward as more kenyon cells are created. this results in a concentric pattern of cell bodies, with the somata of the last-born cells in the center, where the neuroblast had been, and the somata of the first-born cells at the outermost margins of the cell body area. where a kenyon cell sends its dendrites in the calyces and which lobes it projects its axons to varies based on its birth-order. distinct types of kenyon cells form at specific times during development.
