Evaluation of the Contribution of Signals Originating from Large Blood Vessels to Signals of Functionally Specific Brain Areas

Figure 2

SWI images and activation maps for one subject in whom activation of BOLD and inflow signals appeared in the same image slice. The crossing of the two white lines indicates the center of the FFA. (a) SWI-noMIP (left) and SWI-MIP (right) images. (b) Activation maps on the SWI-noMIP of the FFA by BOLD signals using the contrast of the face and scene conditions () (left) and an activation site caused by inflow (S0) signals using the contrast of the face and control conditions () (right). (c) Activation maps on the SWI image using (left) and (right). A: anterior; L: left. (uncorrected).
