Alternative definition : KEGG: Axon guidance represents a key stage in the formation of neuronal network. Axons
are guided by a variety of guidance factors, such as netrins, ephrins, Slits, and
semaphorins. These guidance cues are read by growth cone receptors, and signal transduction
pathways downstream of these receptors converge onto the Rho GTPases to elicit changes
in cytoskeletal organization that determine which way the growth cone will turn.;
