Parcellation brain
WebA diffusion tensor study of a predefined brain parcellation using graph-theoretical methods showed increased efficiency and connectedness within the right hemisphere, but with regions of greatest network centrality in the left hemisphere [14]. ... Brain regions with more gray matter in one hemisphere may develop lateralization of brain ... WebAccurate whole brain parcellation may lead to more accurate macroscale connectomes for the normal brain, which can then be compared to disease states. Pathways through cerebral white matter can be charted by histological dissection and staining, by degeneration methods, and by axonal tracing.
