In this study, magnetic resonance (MR) images of the brain of an adult common dolphin ( Delphinus delphis ) were acquired in the coronal plane at 66 antero‐posterior levels. From these scans a computer‐generated set of resectioned virtual images in orthogonal planes was constructed using the programs VoxelView and VoxelMath (Vital Images, Inc., Michigan State Univ.). Sections in all three planes reveal major neuroanatomical structures. These structures in the adult common dolphin brain are compared with those from a fetal common dolphin brain from a previously published study as well as with MR images of adult brains of other odontocetes. This study, like previous ones, demonstrates the utility of MR imaging (MRI) for comparative neuroanatomical investigations of dolphin brains. Anat Rec 268:411–429, 2002. © 2002 Wiley‐Liss, Inc.
