Tree shrews are special relatives of primates from evolution. They are visually oriented animals with well-developed visual system and also possess developed limbic brain structures. For years, they were used as animal models in studies of visual system and social tress. However, few previous studies have used magnetic resonance imaging to study the brain of tree shrew. As an important step to achieve automated/parametric analysis of tree shrew brain imaging data, we built a set of brain tissue probability maps (grey matter, white matter and cerebrospinal fluid) of Tupaia belangeri chinensis and used for semi-automated volumetric measurements of limbic brain structures.
