The document proposes a memory retrieval device that would store a person's optical nerve impulses corresponding to memories. The device would consist of a small wire implanted in the optic nerve and a visual processor implanted in the arm to control memory retrieval. The intended uses are to help Alzheimer's patients regain access to memories and provide an objective source of evidence for courts. The device could also be used for educational purposes by making memories publicly accessible online. Some concerns addressed are the technical challenges of converting nerve impulses to visual images and preventing interference during memory retrieval.
