title: Wiring mechanisms for olfaction and vision--not completely different after all.
abstract: Gradients of repulsive EphrinAs in the target were thought to repel temporal retinal ganglion cell axons expressing high levels of EphA receptors. Now, in this issue of Neuron, Suetterlin and Drescher (2014) show that EphrinA expressed on nasal axons contributes to the repulsion of temporal axons.
