Figure 2.

Figure 2

Hippocampal shape differences showing statistically significant (P <.05: surface point-wise, without multiple comparison correction) deformations in the surface maps of PHS compared to healthy controls (Panel A) and PHS compared to nonpolydipsic patients (Panel B) Note the inward deformations on the bilateral anterior lateral surfaces in PHS (A,B: blue), and on the right anterior medial surface in NNS (B: orange).

Mean eigenvectors capture discrete shape differences across groups. The figure shows group mean (± SD) magnitude of the 5th eigenvectors for the hippocampus (A) and amygdala (B). Note the magnitudes parallel the neuroendocrine responses in Figure 4 which were the basis for the predicted linear contrast (PHS>PNS>HC>NNS). See Figures 1C,D and 3 C,D for maps of the extreme values of these eigenvectors and to assess their overlap with the corresponding surface maps. Vector magnitude PHS>PNS>HC>NNS: #P < .01; * p < .10 (Bonferonni corrected for multiple comparisons).
