下線部Dと答え.ウはなぜ同じ用法なんでしょうか 教えてください🙏

closer to reality. Researchers have investigated the use of electricity to stimulate vision for nearly half a century. In the 1960's, a *physiologist implanted 80 electrodes on the surface of a blind person's *visual cortex, a region at the back of the brain. Wireless stimulation of the electrodes made the patient see spots of light known as *phosphenes. This is the first stop for visual signals coming from the eye. (D) By the 1980's, a crop of *ophthalmologists began considering a narrower and seemingly easier-to-solve problem: making *prostheses for the eye. They suggested that degrade *photoreceptor cells called *rods and cones, still leave large portions of the retina intact even after a patient has become totally blind. The way to stimulate the remaining functional cells was proved *feasible in the mid-1990's. A device consisting of a tiny video camera perched on the bridge of a pair of glasses, a belt-worn video processing unit, and an electronic box, was developed recently. The electronic box issues signals to an implant behind the patient's ear that has wires running to a grid of 16 electrodes affixed to the output layer of the retina. The video processor wirelessly transmits a simplified picture of what the camera images to the box, and then the retinal implant stimulates cells in a pattern roughly reflecting that information.
