Mice can see again! Visual activity regenerates neural connections between eye and brain

A study in mice shows for the first time that visual stimulation can help damaged retinal neurons regrow optic nerve fibers (retinal ganglion cell axons). In combination with chemically induced neural stimulation, axons grew further than in strategies tried previously. Treated mice partially regained visual function. The study demonstrates that adult regenerated CNS axons are capable of navigating to correct targets in the brain.
