It’s 2011 and we still don’t have cyborg implants available. This is a sad state because the technology was being worked on a decade ago. One of the least know studies was done at UC Berkeley by Garrett Stanley, Fei Li and Yang Dan. In their experiment they tapped into the lateral geniculate nucleus of a cat. This is inside the thalamus which is the sensory processing unit of the brain. They used a linear decoding technique to convert the signals coming from 177 cells into actual images. Now the image quality is actually dependant off of how many cells you record from. It’s a lot like a bit rate concept. The more samples you take, the higher the quality.
