Efficient Spatial Estimation of Perceptual Thresholds for Retinal Implants via Gaussian Process Regression
Roksana Sadeghi, Michael Beyeler
Retinal prostheses restore vision by electrically stimulating surviving neurons, but calibrating perceptual thresholds (i.e., the minimum stimulus intensity required for perception…

Simulated prosthetic vision confirms checkerboard as an effective raster pattern for epiretinal implants
Justin M. Kasowski, Apurv Varshney, Roksana Sadeghi +1
Spatial scheduling of electrode activation ("rastering") is essential for safely operating high-density retinal implants, yet its perceptual consequences remain poorly understood.…
