Sequence of visual cortex stimulation affects phosphene brightness in blind subjects Open
We showed evidence of temporal interactions in non-overlapping sequences of electrodes, where the direction of the effect was subject specific but consistent across a variety of electrode locations and current amplitude levels.

Multi-electrode stimulation evokes consistent spatial patterns of phosphenes and improves phosphene mapping in blind subjects Open
Relative mapping methods, combined with bimanual fixation, resulted in the most precise estimates of phosphene organization. These techniques, combined with use of a standard logarithmic model of visual cortex, may provide a practical way …

Retinotopic to Spatiotopic Mapping in Blind Patients Implanted With the Argus II Retinal Prosthesis Open
The brain accurately maps the artificial vision induced by a retinal prosthesis based on instantaneous gaze position. Remapping based on eye position is feasible and will increase visual stability in prosthetic vision.

Improvements in vision‐related quality of life in blind patients implanted with the Argus II Epiretinal Prosthesis Open
Patients whose vision negatively affected them with respect to three VisQoL dimensions (that is, getting injured, coping with the demands of their life and fulfilling their life roles) reported significant improvement in QoL after implanta…
