New researchout of Germany is helping to pinpoint details of how the mammalian retina converts incoming light into digital signals which ultimately make their way to the brain. Before the information is shipped off to the brain, however, it undergoes massive processing which, among other things, helps to extract features present in the incoming image. It is so complex that we are still a long way from understanding how it all works. The new research, as one report explains, “show that the retina is by no means as well understood as is commonly believed.” We have discussed some of the complexities of converting the incoming light into digital signals to be sent to the brain here, here andhere. There is no doubt much yet to learn about this incredible image processing capability, but what we do know indicates it is profoundly sophisticated. As the report explains: Read more
