During development, the growing tips of neurons must locate and identify their preferred targets. Neurons follow attractive and repulsive guidance signals to build a network to connect muscle activity to brain signals, sensory inputs to behavioral responses, and so on. Fujisawa et al. have now discovered another component, EVA-1, in the guidance system for neurons that fine-tunes the guidance signals sent and received by different neurons in the model organism Caenorhabditis elegans.
