Beware of crossing axons.

During development, growing axons frequently cross the midline of the body to connect the two sides of the nervous system. This process requires the Robo3 receptor, which is mutated in people suffering a rare congenital disorder. Conditional elimination of Robo3 from selected subsets of neurons in the mouse provides a model of this congenital strabismus and sheds light on the need for correct axon guidance in the development of specific behaviors (see Renier et al., e1000325).
