# BARseq **Expanded name:** Barcoded Anatomy Resolved by Sequencing **Entity class:** Spatial transcriptomic and projection-mapping method **Collections:** [[collections/Neurotech|Neurotech]] · [[collections/Consciousness Continuity|Consciousness Continuity]] ## Definition **BARseq** uses nucleic-acid barcodes and in-situ sequencing to relate neuronal gene expression and spatial identity to long-range projection patterns at scale. ## Relationships - BARseq complements [[wiki/MERFISH|MERFISH]] and [[wiki/Patch-seq|Patch-seq]] by joining molecular classification to anatomical projection information. - Its measurements contribute to reference atlases and [[wiki/Connectomics|connectomic]] interpretation, but they do not replace synapse-level wiring or dynamic neural-state capture. - The method is routed from [[articles/Technologies for Consciousness Mapping and Transfer|Technologies for Consciousness Mapping and Transfer]] and links back to [[collections/Neurotech|Neurotech]].
