A group of researchers from the Netherlands and Spain have demonstrated that cortical neurostimulation from a high-count implanted electrode array can meaningful visual perception. In a study recently published in Science, the team has shown that composite electrical stimulation of the primary visual cortex can produce the perception of shapes, and that a sequence of […]

Professor Gregg Suaning, School of Biomedical Engineering, The University of Sydney, explains the Phoenix 99 bionic eye project. By delivering small amounts of electric current via an electrode array implanted into the eye, it is possible to elicit visual sensations in blind subjects.
