Visual cortex responses to suprachoroidal electrical stimulation of the retina: effects of electrode return configuration.

abstract：OBJECTIVE:Neuromodulation technologies are increasingly used for improving function after neural injury. To achieve a symbiotic relationship between device and user, the device must augment remaining function, and independently adapt to day-to-day changes in function. The goal of this study was to develop predictive co...
