Cell Type - Bryant McGill

# Cell Type **Entity class:** Concept or analytic term **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.

The tier labels apply to the inference, not automatically to every factual anchor inside it. The interpretive frame comes from [[articles/Technologies for Consciousness Mapping and Transfer|Technologies for Consciousness Mapping and Transfer]] and [[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]]. Collection route: [[collections/Neurotech|Neurotech]]. - **INF-0046 — Analytic.** Enhancer-driven expression lets a modality address a cell type rather than a volume, which is a form of logical addressing overlaid on physical space. The nervous system becomes a network with types as addresses, and that is a far more powerful abstraction than coordinates.
