title: Cadherins as matchmakers.
abstract: Cadherins implement afferent-target matching in invertebrates, but proof for this concept in mammalian circuits has remained elusive. Two new studies in this issue of Neuron show that cadherin-6 mediates retinal ganglion cell target selection and that cadherin-9 promotes synapse specificity in the hippocampus.
