This encounter leads to reorientation of the sensory axon trajectory, and tracking of the sensory growth cone along the length of the motor axon shaft. Sensory growth cone (DiI: red), interjecting motor axon (GFP: green). Note: tracking is typically accompanied by numerous transient sensory growth cone filopodial-motor axon membrane contacts. Full protocol described in:
