Growth cones are the specialized tips of neuronal axons that make their way through the nervous system in search of a correct target. In his Perspective, Caroni outlines the signaling mechanisms that help steer the growth cone as it moves, and discusses a report by Song et al. in this week's issue that completes our understanding of how the cell is attracted or repulsed by various molecules in its environment.
