PMBSF Procrustes superimposition in ne-Emx2 mice. (7A) Procrustes superimposition of 26 barrel landmarks from C57BL/6J (blue) and DBA/2J (red) emphasizing the strain means from Figure 3 above. (7B) Procrustes superimposition of barrels from one wild-type mouse (blue) and one ne-Emx2 mouse (red) from figure 3 of  (original figure provided by D.D. O'Leary). In 7B we note two main shape differences. The first is highlighted by the gray box. Wild-type PMBSF shows lateral stretching relative to ne-Emx2 mice for the posterior parts of barrel rows A to E. Second, in the area not highlighted by the gray box (anterior ends of rows C, D, and E), there is rostral stretching in ne-Emx2 mice. This aspect is similar to the effect seen in DBA/2J versus C57BL/6J.
