Scientists develop 'bionic eye' which could restore sight to the blind
- Researchers have dramatically boosted the performance of retinal implants by cracking a “code” that communicates visual signals to the brain.
The code consists of specific patterns of electrical pulses. By incorporating it into their device, the scientists came close to restoring normal vision in totally blind mice lacking any light-sensitive cells.
Tests showed that the animals were able to discern facial features and track images with their eyes.
