# Gislin Dagnelie **Domain:** Vision Science / Visual Prostheses **Doc Type:** Person Node **Affiliation in Source:** [[wiki/Johns Hopkins University|Johns Hopkins University]] **Primary Source:** [[articles/2026 Annual Report on Brain-Computer Interfaces|2026 Annual Report on Brain-Computer Interfaces]] ## Relevance **Gislin Dagnelie** appears in the annual report as a Johns Hopkins vision-prosthetics expert commenting on claims about cortical visual restoration. His role in the cluster is to mark the clinical and perceptual distance between an announced device trajectory and demonstrated human visual performance. ## Epistemic role The source pairs Dagnelie with [[wiki/Philip Troyk|Philip Troyk]] in cautioning that predictions of high-resolution, infrared, or better-than-natural vision remain speculative pending clinical evidence. The relevant standard is not whether cortical stimulation can evoke percepts, but what those percepts reliably support over time for a person using the system. ## Relationships **Related cluster nodes:** [[wiki/Johns Hopkins University|Johns Hopkins University]] · [[wiki/Intracortical Visual Prosthesis Project|Intracortical Visual Prosthesis Project]] · [[wiki/Neuralink|Neuralink]] · [[collections/Neurotech|Neurotech]]
