Blind Mice, No Longer


Optogenetics is a technique that allows researchers to control brain cell activity using light.

In a study published on April 19, 2011 in the journal Molecular Therapy, researchers at the McGovern Institute for Brain Research at MIT and the University of Southern California used optogenetic technology to restore vision in blind mice. This video illustrates how it was done.
