Electrocorticography - Bryant McGill

# Electrocorticography **Entity class:** Concept or analytic term **Domain:** Neurophysiology / Invasive Neural Interfaces **Doc Type:** Scientific Concept Node **Maturity:** Established Clinical Method **Related:** [[Invasive BCI]], [[Neural Decoding]], [[DICOM]], [[Neurodata Without Borders]] --- ## Definition **Electrocorticography (ECoG)** records electrical activity using electrodes placed on the cortical surface. It provides stronger and more spatially specific signals than scalp EEG while remaining less spatially granular than many penetrating intracortical arrays. ## Interface relevance ECoG is important for seizure localization, cortical mapping, speech decoding, and BCI research. Its clinical context, electrode geometry, sampling configuration, timing, and surgical provenance are necessary parts of any reusable neural record. ## Neurotech source route **Collection:** [[collections/Neurotech|Neurotech]] **Source article:** [[articles/The Organic-Synthetic Brain Atlas|The Organic-Synthetic Brain Atlas]] ## Relationships [[wiki/Electrocorticography|Electrocorticography]] is related to [[wiki/Brain-Computer Interfaces|Brain-Computer Interfaces]] as cortical-surface electrical recording for high-bandwidth decoding.  This entry's documented connections are expressed in its definition and related-work routes, with provenance retained in the source-linked material.  ## 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  - In [[articles/The Organic-Synthetic Brain Atlas|The Organic-Synthetic Brain Atlas]], **Movement VI — Semantic Translation: Neural Activity in Language-Model Space** provides the narrative context for **Electrocorticography**: Wiki route: semantic neural decoding · generative BCI decoding · cross-modal decoding · ECoG speech decoding. - In [[articles/The Organic-Synthetic Brain Atlas|The Organic-Synthetic Brain Atlas]], **VI.4 — Speech Decoding from Implanted Electrocorticography** provides the narrative context for **Electrocorticography**: A parallel and substantially more developed line of work decodes attempted speech directly from invasive electrode arrays placed on the cortical surface — electrocorticography (ECoG) — in patients with severe motor impairments… - In [[articles/The Architecture of Continuity and Emerging Neuroinformatics Standards|The Architecture of Continuity and Emerging Neuroinformatics Standards]], ****3\.
