WebJan 6, 2024 · Axon regeneration and sprouting refer to differences in the origin of a regenerating axon; a newly regenerating axon arises from the injured axon itself, whereas sprouting refers to collaterals extending from spared axons that were not severed by the injury (Figure 3 C) (reviewed in Fischer et al., 2024; Steward and Willenberg, 2024). The ... WebJan 1, 2024 · Consistent with observations by Aguayo et al. (1981), this suggests that the CNS environment is a major reason for the failed regeneration of severed axons.
