5 Questions for the Brain’s Code-Breaker

So how are you tapping into the code to restore vision?

We can bypass damaged cells using light to signal output neurons directly. The first step is genetically engineering the output cells to be light-sensitive. Then we convert images into a codelike pattern of light pulses that activates the modified genes and causes the output cells to fire off a message to the brain.

How would your technique work in the real world?
Patients would get a quick injection to implant the genes. They would then wear glasses outfitted with a camera and a microprocessor to convert what they “see” into patterns of light that would restore the communication link between the eyes and the brain. Patients might look a little Star Trek-y but should have near-normal vision.
