WebApr 11, 2024 · Increasing the degree of spatial smoothing of the fMRI data enhanced the correlation between individual voxel time-series and the GM mean time-series. These results suggest that signal-to-noise factors may be limiting the accuracy of voxel-wise timing estimates and hence their agreement between the two data segments. In conclusion, … WebA file with multiple maps of the same contrast (Faces - Hands) after different combinations of spatial smoothing and temporal filtering. 1) Select File/Open, and open the anatomical …
