Figure 3. Visualizations of probabilistic fiber tracking results.

(a) Sagittal view from the left. (b) Coronal view from the front. (c) Oblique view. The images show 500 streamlines per seed voxel in the right STN of one subject, color-coded for streamline direction (red  =  left-right, green  =  anterior-posterior, blue  =  inferior-superior). The right STN seed is represented by the white surface, indicated by the white arrow. Abbreviations: acc  =  anterior cingulate cortex, cc  =  corpus callosum, ifg  =  inferior frontal gyrus, phg  =  parahippocampal gyrus, sfg  =  superior frontal gyrus, sma  =  supplementary motor area, stg  =  superior temporal gyrus.
