# Functional Magnetic Resonance Imaging **Entity class:** Concept or analytic term **Domain:** Neuroimaging / Computational Neuroscience **Doc Type:** Scientific Concept Node **Maturity:** Established **Related:** [[Non-Invasive BCI]], [[wiki/Brain Imaging Data Structure|Brain Imaging Data Structure]], [[Neural Decoding]], [[Multimodal Neural Data]] --- ## Definition **Functional magnetic resonance imaging (fMRI)** maps brain activity indirectly through blood-oxygen-level-dependent and related hemodynamic signals. It offers broad spatial coverage and millimeter-scale localization but lower temporal resolution than electrophysiological methods. ## Interface relevance fMRI is used for functional mapping and semantic decoding as well as clinical and research imaging. Voxel coordinates, acquisition sequences, timing, preprocessing, events, and subject context are required to interpret a derived activation pattern. ## 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]] · [[articles/The Organic-Synthetic Brain Atlas|The Organic-Synthetic Brain Atlas]] ## Relationships [[wiki/Functional Magnetic Resonance Imaging|Functional Magnetic Resonance Imaging]] is related to [[collections/Neurotech|Neurotech]] through [[articles/The Architecture of Continuity and Emerging Neuroinformatics Standards|The Architecture of Continuity and Emerging Neuroinformatics Standards]] and [[articles/The Organic-Synthetic Brain Atlas|The Organic-Synthetic Brain Atlas]]. <!-- 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 Organic-Synthetic Brain Atlas|The Organic-Synthetic Brain Atlas]], **Movement V — Functional Integration and Readout: Activity, Imaging, and Dynamic Coupling** provides the narrative context for **Functional Magnetic Resonance Imaging**: Wiki route: neural signal acquisition · fMRI · fNIRS · functional ultrasound · Neuropixels · optogenetics and chemogenetics. - In [[articles/The Architecture of Continuity and Emerging Neuroinformatics Standards|The Architecture of Continuity and Emerging Neuroinformatics Standards]], ****3\.
