Scientists Create Brain Implant that Enables Identification of Letters

Vision, News

A group of researchers in Spain collaborated with scientists at the Netherlands Institute for Neuroscience in Amsterdam and the University of Utah in Salt Lake City, US, to use a microelectrode array to help a blind person perceive letters and shapes. The implant, which is about the size of a penny, bypasses the optic nerve and instead provides stimulation to the brain’s visual cortex. By the end of the study, the participant could identify several letters. Although the device is in the early stages of clinical development, the first experiment in a human participant was successful. The results now appear in The Journal of Clinical Investigation. Read more via Medical News Today.

Visual Percepts Evoked with an Intracortical Microelectrode Array

Vision, Scholarly Article

Researchers in Spain created a visual prosthesis for end users who are blind to perceive shapes and letters. The team's end user collaborator, Berna Gomez, has experienced blindness for the last 16 years. The implanted visual prosthesis system utilizes the Utah electrode array, which is much smaller than a penny, to create electrical stimulation in Gomez's visual cortex.
