Automated EEG and sEEG Electrode Localization and Labeling in Brainstorm

Brisbane Convention & Exhibition Centre 

Accurate electrode localization is essential for neuroimaging applications, including scalp EEG and stereo-EEG (sEEG). For EEG, precise knowledge of electrode positions facilitates cortical current density mapping and source localization[1]. In sEEG, accurate electrode contact localization enables seizure onset zone (SOZ) identification, which is critical for epilepsy surgery. Traditional methods such as manual digitization or landmark-based techniques are labor-intensive, prone to human error, and require expert involvement. This study introduces automated EEG and sEEG electrode localization workflows within Brainstorm[2], an open-source neuroimaging platform, enhancing accuracy, efficiency, and accessibility for both research and clinical applications.
