Absolutely! sEEG is great for localizing the seizure onset zone. However, ECoG offers broader spatial coverage, which is crucial for mapping in complex cases where the identification of eloquent areas has higher relevance. This ensures better surgical planning and patient safety.
While sEEG has rapidly become our βgo toβ option for localization, grids still have a role - particularly in mapping. This is a pt with a left frontal dysplasia radiographically abutting Broca. While you can map with sEEG, imho grids give you greater spatial coverage.
