Population geodesic trajectory of longitudinal dODFs superimposed on generalized fractional anisotropy (GFA) in early developing infants sampled at different ages. Red, green, blue and yellow boxes show changes in the genu of corpus callosum (GCC), the anterior limb of the internal capsule (ALIC), the splenium of corpus callosum (SCC) and the region with crossing fibers where corticospinal tracts and corpus callosum (CC) pass, respectively. Larger glyphs are used for enhanced visualization.
