Select and Cluster: A Method for Finding Functional Networks of Clustered Voxels in fMRI
Table 3
Comparison of SVD results for the set of ROIs voxels, the reduced set from multiscale analysis, and the whole cortex voxel dataset. For the three tasks and all subjects the maximally stimulus-correlated component was extracted and the following descriptive values were calculated: (i) mean correlation coefficient absolute value; (ii) mean percentage of variance accounted by the component. The descriptive values mentioned were calculated on two sets of voxels, respectively, before (all cortical voxels) and after multiscale correlation analysis method (reduced set of voxels).
