Figure 3: Intracranial VS LFP synchronized with continuous affect estimation during DBS programming for OCD.

Figure 3:

Data shown corresponds to the initial DBS programming session for participant P5. (A) Video of the face (used with permission) was used to do automatic 3D face tracking. Arrows indicate the tracked three degrees of freedom of head pose. The contours of tracked key facial parts are highlighted in green. The three video frames (1, 2, and 3) shown correspond to the timepoints indicated by the vertical lines. (B) Estimation of positive affect on a scale of zero to five based on facial action units 6 and 12. (C) Estimation of head velocity in terms of yaw and pitch in units of degrees of displacement per second. (D) Blood volume pulse (BVP) and electrocardiogram (ECG). (E) 64 channel EEG. (F) DBS amplitude. (G) Bilateral (left and right hemisphere) ventral striatum LFP recordings. (H) RC+S® acceleration (xyz).
