Stereo-electroencephalography (sEEG) is a method that uses stereotactically implanted depth electrodes for extra-operative mapping of epileptogenic and functional networks. sEEG derived functional mapping is achieved using electrical cortical stimulations (ECS) that are currently the gold standard for delineating eloquent cortex. As this stands true especially for primary cortices (e. https://tvtdogiq3erw8r.tokka-blog.com/35182780/the-ener-supply-project-and-preliminary-analysis-of-the-state-of-the-art-and-the-action-plan-for-res-potential-map-building
