"A molecular on-off switch that controls how a mouse brain responds to
vision loss has been discovered by biologists," reports Science Digest. "When the switch is on,
the loss of sight in one eye will be compensated by the other eye, but
also by tactile input from the whiskers. When the switch is off, only
the other eye will take over. These findings may help improve patient
susceptibility to sensory prosthetics such as cochlear implants or
bionic eyes." Read more.
