• Researchers implanted an intracortical microelectrode array consisting of 96 electrodes in the visual cortex of a 57-year-old person with complete blindness for a 6-month period, Over the course of the study, the participant became able to identify phosphenes in a certain space. By the end of the study, when the team simultaneously stimulated up to 16 electrodes in different patterns, the participant was able to identify multiple letters and even tell the difference between some uppercase and lowercase letters.
