A visual cortex prosthesis for form recognition
2020
Baylor College of Medicine, Houston, USA
The authors developed a visual cortex prosthesis in which shapes were traced on the surface of visual cortex by stimulating electrodes in a dynamic sequence. In both sighted and blind participants, dynamic stimulation enabled accurate recognition of letter shapes predicted by the brain’s spatial map of the visual world. Forms were presented and recognized rapidly by blind participants, up to 86 forms per minute. These findings demonstrate that a brain prosthetic can produce coherent percepts of visual forms.
