title: The axon's balancing act: cis- and trans-interactions between Ephs and ephrins.
abstract: Ephrin ligands are known to be coexpressed with Eph receptors in certain populations of axons. In this issue of Neuron, Kao and Kania demonstrate the importance of ephrin/Eph cis-interaction for correct pathway selection by spinal motor axons in vivo.
