Mean (standard deviation) across samples for each white matter tract and gray matter (GM). From histology: MF, myelin fraction; MyTh, myelin thickness; AxD, axon diameter. From multi-exponential T2: MWF, myelin water fraction; MWT2, myelin water T2; OWT2, other water T2. From quantitative magnetization transfer: PSR, macromolecular pool-size ratio; kmf, macromolecular to free water magnetization transfer rate.
