Figure 3

The grey lines intersect at the origin of the origins of the standard coordinate system23 used for the orientation of the specimen. The blue line indicates the most anterior level of the temporal lobes (the temporal poles, which are damaged are not shown in this image). The orange rectangle represents the bounding box that contains the posterior spared hippocampus (outlined in green), the widest extent of which is at a more medial level than this image shows. The black arrows identify the level at which a surgical clip was positioned on a blood vessel. The red arrows indicate the presence of lesions in the subcortical WM. AC, plane of the anterior commissure; PC, plane of the posterior commissure; AC–PC, ideal plane at the level of both the AC and PC; Ce, cerebellum; LG, lateral geniculate nucleus; Pu, putamen; TP, temporal pole; RH, right hemisphere; LH, left hemisphere. Scale bar, 1 cm.
