The study furthers what it calls a "long-held dream of scientists," to impart a rudimentary form of sight to blind people by sending information directly to the brain's visual cortex.
In the experiment, a neurosurgeon implanted a microelectrode array into the visual cortex of Berna Gómez, a former teacher who has been blind for more than 16 years.
After a training period, Gómez was able to decipher visual information that was fed from the camera directly to her brain.
At the time of the study, Gómez was 57 years old.
The researchers say previous studies have found around 700 electrodes could give a blind person enough visual information to boost their mobility to a useful extent.
