Visual assessment of top 4 independent components identified in rsfMRI by surface-based ICA. Top: left hemisphere, bottom: right hemisphere. The components generally appear similar but their local patterns are different. IC-1(b) captured by HSD is more dispersed over the parietal lobe than that by FreeSurfer; IC-4 captured by HSD is more concentrated along frontal sulcus than that by FreeSurfer. This discrepancy is possibly due to registration distortion, by which surface tessellation shrinks/expands cortical area.
