Experimental visual prosthesis
Abstract
Of the methods available which seek artificially to replace the sensory input lost through blindness, the approach which should ultimately be of greatest value is that by which visual information is fed directly to the brain. The paper reviews earlier work in this field and describes a new prosthesis which gives grounds for optimism.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
