Anatomical diversity across vertebrate species is showcased in the Animal Brain Collection. T2-weighted MR images in coronal and/or horizontal planes illustrate interspecies variation in brain morphology across six representative species: lamprey, hagfish, gecko, Japanese fire belly newt (Cynops pyrrhogaster), mouse, and gentoo penguin. These examples span a broad phylogenetic range, from jawless vertebrates to reptiles, amphibians, birds, and mammals, highlighting differences in brain size, shape, and internal architecture.
