# Functional Magnetic Resonance Imaging **Domain:** Neuroimaging / Computational Neuroscience **Doc Type:** Scientific Concept Node **Maturity:** Established **Related:** [[Non-Invasive BCI]], [[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.
