Through the optimization of
simultaneous multislice (SMS) technique, a 0.8mm3 whole brain resting
state fMRI data with minimum distortion was acquired to show the benefit of doing
fMRI study at ultra-high field.
Figure 2: a) default mode network
using 4mm smoothing (top) and 2mm smoothing (bottom). b) selected slices of the
default mode network around the PCC using 4mm smoothing (top) and 2mm smoothing
(bottom). Both display t-values using thresholds p(FWE-voxelwise)<0.05,
cluster extent>300 voxels for 4mm smoothing and p(FWE-clusterwise)<0.05,
cluster extent>500 voxels for 2mm smoothing.
