The Spatial Extent of Epiretinal Electrical Stimulation in the Healthy Mouse Retina

Conclusion: The existence of significant hysteresis requires that future investigations of electrical retinal stimulation control for such long-memory adaptation. The spread of electrical activation beyond 200 µm suggests that neighbouring electrodes in epiretinal implants based on indirect stimulation of RGCs may be indiscriminable at interelectrode spacings as large as 400 µm.Neurosignals 2017;25:15 –25
