Extending Local Canonical Correlation Analysis to Handle General Linear Contrasts for fMRI Data
Figure 7
Activation maps for the contrast V-F of the visual paradigm using corrected -values (). The GLM-GS method yields the smoothest activation map at the expense of showing activations reaching outside of gray matter. The GLM-NS method preserves activations in gray matter much better but with unappealing broken links among activated voxels. The activation map using cCCA-RG provides a compromise between the smooth appearance of activations and preservation of fine cortical structure.
