Head Models. (A) Head model generated from the T1W structural scan of a subject using Free Surfer. Each protrusion on the scalp is an EEG electrode. (B) Clusters of vertices with high curvature are used to generate the position of the potential electrodes. Different clusters are depicted using different colors. (C) Using the curvature information of the head model, we can identify electrodes using the proposed method.
