How axons change chemical cues to mechanical force

Neural networks in the brain form by an axon extending from one neuron to interact with another. Chemical cues in the neuron microenvironment are responsible for activating the extending axon, but which molecular factors are responsible for interpreting this chemical information into a mechanical force for the axon to reach its destination has been unclear. Researchers at the Nara Institute of Science and Technology show shootin1 to be this mysterious factor.
