A US-based research team has successfully demonstrated how dynamic stimulation of the visual cortex enables blind and sighted people to “see” shapes – a technique that could one day be used to convey ...

Using auditory or tactile stimulation, Sensory Substitution Devices (SSDs) provide representations of visual information and can help the blind "see" colors and shapes. SSDs scan images and transform ...

For most adults who lose their vision, blindness results from damage to the eyes or optic nerve while the brain remains intact. For decades, researchers have proposed developing a device that could ...

A team of investigators has described an approach in which implanted electrodes are stimulated in a dynamic sequence, essentially 'tracing' shapes on the surface of the visual cortex that participants ...
