Can cns regenerate

Unlike peripheral nervous system injury, injury to the central nervous system is not followed by extensive regeneration. It is limited by the inhibitory influences of the glial and extracellular environment. The hostile, non-permissive growth environment is, in part, created by the migration of myelin-associated inhibitors, astrocytes, oligodendrocytes, oligodendrocyte precursors, and microglia. The environment within the CNS, especially following trauma, counteracts the repair … WebMany forms of brain and spinal cord (CNS) damage cut axons. Where axons can regenerate, as in peripheral nerves, they can bring back function. However in the CNS axon regeneration fails. This is the main …
