Temporo-Parietal White Matter Pathway Asymmetry Underlies Functional Laterality

White matter pathway asymmetry was investigated using diffusion tensor tractography in a normalised image dataset of 30 right handed young healthy individuals for pathways passing between the temporal and parietal lobes. We identified, for the first time, a rightwardly asymmetric pathway connecting the posterior part of the temporal lobe to the superior parietal lobule. This pathway may be related to auditory-spatial function for which there is evidence for a rightward laterality from functional imaging studies and may also be implicated in verbal and auditory spatial working memory function.
