# Language BCI **Entity class:** Brain-computer interface class **Collections:** [[collections/Neurotech|Neurotech]] · [[collections/Consciousness Continuity|Consciousness Continuity]] ## Definition **Language BCI** is a BCI designed to decode, restore, or synthesize linguistic communication from neural activity. ## Relationships - **Technical relationship:** It relates to [[wiki/BrainLLM|BrainLLM]], [[wiki/Neural Representation Alignment|Neural Representation Alignment]], and [[wiki/Brain-Computer Interfaces|Brain-Computer Interfaces]] while preserving the boundary between intended communication and arbitrary private thought. - **Source relationship:** This entry is routed from [[articles/Technologies for Consciousness Mapping and Transfer|Technologies for Consciousness Mapping and Transfer]] and the [[research/Consciousness Mapping and Transfer Ecosystem Relationship Graph - 2026-09-10|Consciousness Mapping and Transfer Ecosystem Relationship Graph — 2026-09-10]]. - **Collection relationship:** The entry belongs to [[collections/Neurotech|Neurotech]] and the person-scale persistence questions maintained by [[collections/Consciousness Continuity|Consciousness Continuity]]. ## Epistemic boundary Inclusion in the continuity stack records a documented component, method, model, or analytic distinction; it does not by itself establish whole-person transfer, subjective continuity, or numerical identity.
