Although callosal connections have been shown to link extensive regions of primary visual cortex, the distribution of these connections with respect to the map of visual space and the map of orientation preference remains unclear. Here we combine optical imaging of intrinsic signals with injection of fluorescent microspheres to assess the functional specificity of callosal connections in the tr...

BACKGROUND Hepatitis E virus (HEV) is a major cause of hepatitis in developing countries and poses a threat to public health worldwide. Tree shrew (Tupaia belangeri chinensis) is a useful animal model in studies on hepatitis viruses, such as hepatitis B and C viruses. However, the use of this animal model for HEV research is yet to be developed. METHODS Tree shrews were intravenously (IV) inj...

Diverse fungal species live on the surfaces of plant tissues, some of which presumably occur in a mutualistic association. Some fungal species are widespread and can be found in many different animal species, whereas others are highly specific to single hosts. In this study, we investigated the taxonomic identities and phylogenetic relationships of fungal species isolated from tree shrew hair s...
