# Tractography **Entity class:** Concept or analytic term **Domain:** Neuroimaging / Connectomics **Doc Type:** Scientific Method Node **Maturity:** Established with Interpretive Limits **Related:** [[Connectomics]], [[Neural Mapping]], [[Functional Magnetic Resonance Imaging]] --- ## Definition **Tractography** estimates large-scale white-matter pathways from diffusion-weighted imaging. It produces model-dependent streamline reconstructions rather than direct microscopic observations of every axon. ## Architectural role Tractography supplies macro-pathway priors that can guide graph construction and regional hypotheses. Those priors should remain route-conditional and uncertainty-aware because acquisition, modeling, crossing fibers, and parameter choices can create false positives and false negatives. ## Neurotech cluster route **Collection:** [[collections/Neurotech|Neurotech]] **Source articles:** [[articles/The Architecture of Continuity and Emerging Neuroinformatics Standards|The Architecture of Continuity and Emerging Neuroinformatics Standards]] ## Relationships [[wiki/Tractography|Tractography]] is related to [[collections/Neurotech|Neurotech]] through [[articles/The Architecture of Continuity and Emerging Neuroinformatics Standards|The Architecture of Continuity and Emerging Neuroinformatics Standards]]. <!-- BEGIN HUMANIZED RELATIONSHIPS 2026-09-11 --> This entry's documented connections are expressed in its definition and related-work routes, with provenance retained in the source-linked material. <!-- END HUMANIZED RELATIONSHIPS 2026-09-11 --> ## Related Work in the Corpus <!-- BEGIN HUMANIZED CORPUS ROUTES 2026-09-11 --> - In [[articles/The Architecture of Continuity and Emerging Neuroinformatics Standards|The Architecture of Continuity and Emerging Neuroinformatics Standards]], ****1.2 Mind Uploading Frameworks and Biological State Maintenance**** provides the narrative context for **Tractography**: Molecular and dynamical state: tractography · U3 molecular data classes · U10 thermodynamic data classes · neural plasticity · synaptogenesis · phosphorylation signaling · receptor trafficking · proteostasis · RNA editing ·… <!-- END HUMANIZED CORPUS ROUTES 2026-09-11 -->
