Follower neuron

Type of nerve cell in the brain

A follower neuron is a nerve cell that arises in the developmental stage of the brain and which growth and orientation is intrinsically related to pioneer neurons. These neurons can also be called later development neurons or follower cells. In the early stages of brain development, pioneer neurons define axonal trajectories that are later used as scaffolds by follower neurons, which project their growth cones and fasciculate with pioneer axons, forming a fiber tract and demonstrating a preference for axon-guided growth. It is thought that these neurons can read very accurate cues of direction and fasciculate or defasciculate in order to reach their target, even in a highly dense axon bundle.
