Blind Mice Can See Scientists Claim


Scientists have found that 'blind mice' are able to use special photo-sensitive retinal cells to see light, patterns and images. The discovery has shocked researchers who, until now, believed that rod and cone cells were the only ocular cells that could process light in a way that resulted in image formation and perception.

The results of the animal study, published in the journal Neuron, shows that mice that did not have properly functioning rod and cone eye cells were able to use photo-sensitive retinal ganglion cells to produce low acuity images.

Scientists now believe that humans could reproduce this phenomenon by training their own photo-sensitive retinal cells to perform in the same way.
