Between-subject variation versus within-subject variation in the test–retest data. The white matter structures under the study are: cingulum sub-regions of posteroinferior (Cg P), superior (Cg S), and anteroinferior (Cg A), the entire cingulum (Cg), fornix (Fx), corpus callosum sub-regions of genu (CC G), body (CC B), splenium (CC S), and the entire corpus callosum (CC).
