Figure Lengend Snippet: Panels A–D show electrode trajectories; panels E–H depict active contacts for all patients. Structures of interest include the GPi (green) and subdivisions of the STN: motor (orange), sensorimotor (blue), and limbic (yellow). Views are presented from the posterior (A, E) , superior (B, F) , left lateral (C, G) , and right lateral (D, H) perspectives. Panels A, D, E, G , and H display both axial and coronal slices, whereas panels B, C , and F show axial slices only. Electrodes are color-coded by target group: blue for those located within the motor STN (m-STN IN), pink for electrodes adjacent to the motor STN (m-STN ADJ), and gray for electrodes outside the STN target (OFF-Target).
Article Snippet: A wireless EEG headset with dry electrodes (DSI-7, Wearable Sensing) was used to record 6-channel EEG (F3, C3, P3, F4, C4 and P4 of the 10-20 international system, with Pz as reference and Fz as ground) at 300Hz.
