Current retinal prostheses suffer from a lack of spatial specificity, resulting in indiscriminate stimulation of many distinct retinal ganglion cell (RGC) types over a large region. Re-creation of the complex spatiotemporal activity patterns of retinal ganglion cells requires single-cell spatial resolution, which is difficult to achieve with monopolar stimulation, even using high-density electrode arrays. Here we investigate the potential of spatial patterns of current injection for improving… CONTINUE READING
