0 indicates no visible damage; 3 (4 for anterior hippocampus) indicates complete absence of area. The rating for each individual patient and the mean of each subject group is listed. HC, Hippocampal; AntTemp, anterior temporal cortex; Amyg, amygdala; PHG, parahippocampal gyrus (corresponding to entorhinal cortex); MBCS, medial bank of collateral sulcus (corresponding to the transition between entorhinal and perirhinal cortex); LBCS, lateral bank of collateral sulcus (corresponding to perirhinal cortex); MBOS, medial bank of occipitotemporal sulcus (corresponding to the transition between perirhinal and isocortex); AntHC, anterior hippocampus; LatTemp, lateral temporal cortex (likely to correspond to TE); PostHC, posterior hippocampus.
Significant difference compared with control mean.
