fasciculation

fasciculation
Tendency of developing neurites to grow along exisiting neurites and hence form bundles or fascicles. Selective fasciculation in developing vertebrate nervous systems is thought to involve the axon-associated cell adhesion molecules L1, F11, contactin, neurofascin and transient axonal glycoprotein TAG-1, and the fasciclins in insect nervous systems.1.
