The brain’s ability to adapt and rewire itself throughout life continues to surprise neuroscientists. Researchers have found a way to restore sight in adult mice with a form of congenital blindness, in spite of the rodents’ relative maturity.
The mice were modeling a rare human disorder of the eye’s retina, called leber congenital amaurosis (LCA), which often causes blindness or severe visual impairment at birth.
This inherited condition seems to be caused by a mutation in any one of dozens of genes associated with the retina and its light-sensing abilities.
