Damage to axons in the central nervous system (CNS) typically results in permanent damage and severed axons in the adult mammalian CNS do not spontaneously regenerate to restore lost functions.  Boosting growth programs can dramatically augment the axon regeneration of injured neurons and if injured neurons can regenerate sufficient number of axons, the CNS may recover and overcome functional deficits.  It is known that G … Continue reading Researchers regenerate damaged nerves via the eye using optogenetics.
