Pairs of tracts that emerged as significantly associated with rearing status were correlated with each other. Abbreviations: FA: fractional anisotropy, RD: radial diffusivity, AD: axial diffusivity, MD: mean diffusivity; L: left hemisphere; R: right hemisphere; Anterior corona radiata = ACR; Body of the corpus callosum = BCC; Cingulum cingulate = CC; External capsule = EC; Fornix crus = FC; Medial lemniscus = ML; Retrolenticular internal capsule = RIC; Superior corona radiata = SCR
