# Electromyography **Entity class:** Concept or analytic term **Domain:** Neurophysiology / Motor Interfaces **Doc Type:** Scientific Concept Node **Maturity:** Established **Related:** [[Neural Interface]], [[DICOM Working Group 32]], [[Multimodal Neural Data]] --- ## Definition **Electromyography (EMG)** records electrical activity associated with skeletal muscle activation. It is not a direct brain recording, but it is often paired with neural data to measure intended or executed movement, evaluate peripheral pathways, and build hybrid control interfaces. ## Architectural role EMG can function as an output correlate, control channel, validation signal, or confound measure. Its synchronization with brain signals is essential when reconstructing sensorimotor intent. ## Neurotech source route **Collection:** [[collections/Neurotech|Neurotech]] **Source article:** [[articles/The Organic-Synthetic Brain Atlas|The Organic-Synthetic Brain Atlas]] ## Relationships [[wiki/Electromyography|Electromyography]] is related to [[wiki/Meta Neural Band|Meta Neural Band]] as measurement of muscle electrical activity for intent decoding. <!-- 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 --> ## 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]] ## Related Work in the Corpus <!-- BEGIN HUMANIZED CORPUS ROUTES 2026-09-11 --> - In [[articles/The Organic-Synthetic Brain Atlas|The Organic-Synthetic Brain Atlas]], **VII.3 — Surface Electromyography and Neuromotor Wristbands** provides the narrative context for **Electromyography**: Meta's Neural Band, announced as part of the Ray-Ban Display ecosystem and the upcoming Orion AR glasses, uses surface electromyography (sEMG) to detect the electrical signatures of intended hand and finger movements at the wrist. - In [[articles/The Architecture of Continuity and Emerging Neuroinformatics Standards|The Architecture of Continuity and Emerging Neuroinformatics Standards]], ****3\.
