Cover Picture: Diffusion tensor imaging of a posnatal day 4 rat: Eigenvectors overlaid on coronal DTI from a P4 rat brain. The orientation and the density of the fibers are shown by the indicated vectors, and the degree of anisotropy is symbolized by the vector length. Fibers that are perpendicular to the image plane are distinguished by the bleu dots. On the left cortex the radial organisation is depicted by the eigenvectors being perpendicular to the pial surface. This radial organisation is disrupted in the right cortex after unilateral hypoxic-ischemic injury. See Sizonenko et al. 2007. Developmental Changes and Injury Induced Disruption of the Radial Organization of the Cortex in the Immature Rat Brain Revealed by In Vivo Diffusion Tensor MRI. Cereb Cortex 17(11):2609–2617.
