Cortical visual implant pre-print announcement! 🌠 Now out in @medrxivpreprint , together with Xing Chen, @Pieters_Tweet et al. Brain implant enterprises such as @neuralink and @Phosphoenix_BV aim to tackle some of the biggest challenges in sensory restoration, like #blindness. In the case of visual neuroprostheses, building a “phosphene map” for each user will be critical to conveying useful visual information to the blind users (aka device calibration). This map matches the ID of each stimulated electrode in the visual cortex to the location of the perceived artificial visual percepts. Our experience with blind volunteers and monkeys shows that high-resolution implants with hundredths to thousands of electrodes can mean hours of tedious and sometimes imprecise or unreliable calibrations for future users. This is a problem! We solved this. I’m happy and proud to present NEUmap: NEural Unsupervised electrode mapping. Want to know more? ... 1/
