How can we design more effective stimulation strategies?

Our lack of understanding of multi-electrode interactions severely limits current stimulation protocols. For example, current Argus II protocols simply attempt to minimize electric field interactions by maximizing phase delays across electrodes using ‘time-multiplexing’. The assumption is that single-electrode percepts act as atomic ‘building blocks’ of patterned vision. However, these building blocks often fail to assemble into more complex percepts.

The goal of this project is therefore to develop new stimulation strategies that minimize perceptual distortions.
