Lateralisation | REDCap

Abbott, Waites, Lillywhite and Jackson 2010 34 Calculated the LI at multiple thresholds, and then calculated at a threshold that yielded a fixed number of active voxels. Calculated the distribution of LI as function of the number of voxels above threshold i.e. obtained a voxel count distribution. Data-driven method (5) Inferior frontal and middle frontal gyri. Laterality should not be determined at a single threshold but using thresholds that yield a fixed number of active voxels i.e. an individualy determined variable threshold, as this is more robust. Argue for the utility of an approach to dominance classification in which an LI distribution across voxel counts for a subject can be compared to a normative distribution.
