Regions showing effective connectivity with each seed region (bold font) are displayed in Figure 7.
For all seed-interacting regions, connectivity was stronger for the crossmodal than the unimodal condition. Brodmann areas (BA) were defined by the Talairach and Tournoux atlas. Cerebellar lobules were defined by the Schmahmann atlas (Schmahmann et al., 2000). Coordinates represent distance in millimeter from anterior commissure: x, right (+)/left (−); y, anterior (+)/posterior (−); z, superior (+)/inferior (−). Regional volumes are expressed in milliliter. B, bilateral hemispheres; L, left hemisphere; R, right hemisphere; SMA, supplementary motor area; MFG, middle frontal gyrus; IFG, inferior frontal gyrus; SFG, superior frontal gyrus.
