title: Of cartridges and columns: new roles for cadherins in visual system development.
abstract: In this issue of Neuron, two papers provide new insights into roles for local cadherin-based interactions during axon targeting in the Drosophila visual system. Using high-resolution analyses, Chen and Clandinin identify nonautonomous roles for the atypical cadherin Flamingo during photoreceptor targeting, while Nern et al. demonstrate that local cell type-specific roles for N-cadherin control layer-specific targeting of lamina neurons.
