Figure 4.

(Left) the hand knob (green $\mathsf{\Omega }$ shape) is a part of the Brodmann area 3b in the central sulcus (between the pre-central (blue) and post-central (red) areas) [10]. (Center) regions of interest (ROIs) for the CM computations; the spherical region of interest (ROI) for detecting the 3b activity in the hand-knob together with the ROI for the thalamic activity detection, including the post-central area (red), thalamus (orange), and brainstem (cyan). (Right) the 24 mm diameter spherical ROI (grey) approximately covers the hand-knob of the left hemisphere. A global MAP estimate for the synthetic EEG data is visualized on the cortex.
