# Cell Type **Collection:** [[collections/Neurotech|Neurotech]] **Type:** Biological ontology concept **Primary sources:** [[articles/2026 Annual Report on Brain-Computer Interfaces|2026 Annual Report on Brain-Computer Interfaces]]; [[articles/The Organic-Synthetic Brain Atlas|The Organic-Synthetic Brain Atlas]] ## Definition A **cell type** is a reproducible biological category defined through some combination of morphology, lineage, gene expression, physiology, connectivity, and function. ## Relationships - [[wiki/FlyWire|FlyWire]] reports 8,453 cell types in its adult female fly reconstruction, with 4,581 described as newly discovered in the source. - Cell-type ontologies can constrain BCI targeting and model priors without making cross-species categories automatically equivalent. <!-- BEGIN HOST RESIDUAL RELATIONSHIP GRAPH 2026-09-10 --> ### Host–residual infrastructure patch — 2026-09-10 **Collections:** [[collections/Consciousness Continuity|Consciousness Continuity]] · [[collections/Neurotech|Neurotech]] · [[collections/Machine Succession|Machine Succession]] **Canonical source article:** [[articles/Mind Uploading and AI — The Host is Reusable and the Person is the Delta|Mind Uploading and AI — The Host is Reusable and the Person is the Delta]] **Related acquisition source:** [[articles/Technologies for Consciousness Mapping and Transfer|Technologies for Consciousness Mapping and Transfer]] **Relationship source:** [[research/Mind Uploading and AI Host-Residual Ecosystem Relationship Graph - 2026-09-10|Mind Uploading and AI Host-Residual Ecosystem Relationship Graph — 2026-09-10]] #### Incoming typed edges - **HR-0311 — [[wiki/Cell-Type Ontology|Cell-Type Ontology]] `wiki_links_to` → this entry** — **EXISTING WIKI EDGE**; evidence `WIKI_ARCHIVE`.

A graph candidate is retained as **CANDIDATE — DO NOT PROMOTE**; similarity, shared personnel, compatibility, adjacent infrastructure, or common requirements do not establish ownership, funding, transfer, operational integration, or shared intent. Software checkpointing, adapters, world models, and confidential computing are engineering precedents or analogues, not demonstrations of human phenomenal or numerical continuity. <!-- END HOST RESIDUAL RELATIONSHIP GRAPH 2026-09-10 -->
