Gislin Dagnelie - Bryant McGill

# Gislin Dagnelie **Entity class:** Concept or analytic term **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]]  This entry's documented connections are expressed in its definition and related-work routes, with provenance retained in the source-linked material.  ## Related Work in the Corpus  - In [[articles/2026 Annual Report on Brain-Computer Interfaces|2026 Annual Report on Brain-Computer Interfaces]], **Neuralink: Operational Clinical Program and Regulatory Trajectory** provides the narrative context for **Gislin Dagnelie**: Regulatory milestones include FDA Breakthrough Device Designation for Blindsight (September 2024)—Neuralink's visual cortex stimulation implant designed to restore vision in individuals who have lost both eyes or optic nerve…
