Regenerating Nerve Fibers (image) Boston Children's Hospital Share Print E-Mail Caption The white areas in this image show extensive regeneration of nerve fibers (axons) in the central nervous system achieved by gene therapy after optic nerve injury. (The blue areas indicate scar tissue.) By adding a potassium channel blocking drug to this treatment, He, Fagiolini and colleagues were able to boost conduction in the regenerated nerves and thereby restore visual function.
