Figure 3.

The corpus callosum displays segment-specific atrophy consistent with the site of injury. Parcellation of the corpus callosum is shown for a representative typical control participant (Fig. 3, top) and for each member of the early injury group (Figs. 3–5). T₁-weighted (for 103 and 104) and T₂-weighted FLAIR (for remaining participants) axial magnetic resonance scans are shown for each person with injury. Black arrows show the primary site of the lesion. In the accompanying graphs, diamonds show the average volume for the typical control group for each segment, for the sum of all segments, for the anterior segments, and for the posterior segments. Bars represent these volumes for each person with early injury. Error bars indicate SEM for the typical control group.
