Figure 1

A significant linear correlation is present between MR measured R1 and histology derived mean axon diameter (R2=0.93, P=0.002), while no such relationship is apparent between R1 and myelin fraction (R2=0.20, P=0.380). Yellow = dCST, green = FG, blue = ReST, teal = RST, red = FC, and purple = VST.
