White matter macrostructural organization and its microstructural composition are two complementary features that may help understand intact brain development, function and brain impairment. The Tractometry framework, which aims to characterise white matter by multi parametric MR metrics, was applied on 3 rat strains (Wistar, SD and Lewis). In this study we examined the impact of rat strain on microstructural features of white matter in the brain, which is suspected to origin from their genetics background.
