Correlation of the lateralisation of white matter microstructure with the behavioural spatial bias.

Statistical Images are overlaid on the FMRIB58_FA standard image. The mean FA skeleton, thresholded at 0.2, is depicted in green shades. Significant cluster is indicated in red-to-yellow (p<0.05, corrected for multiple correlations). A thickened version of the significant cluster is used to facilitate visualization. Positive correlation in the parietal lobe indicates leftward bias correlating with higher FA in the right hemisphere.
