Signalling mechanisms regulating axonal branching in vivo.

The article discusses the signalling mechanisms that regulate axonal branching in vivo in neuronal systems. It focuses on several neuronal systems like the projection of sensory axons into the spinal cord, the corticopontine projection and the retinotectal system. It cites the dorsal root ganglion (DRG) neurons and the retinal ganglion cells (RGC).
