A three-dimensional stereotaxic atlas of the gray short-tailed opossum (Monodelphis domestica) brain.

The gray short-tailed opossum (Monodelphis domestica) is a small marsupial gaining recognition as a laboratory animal in biomedical research. Despite numerous studies on opossum neuroanatomy, a consistent and comprehensive neuroanatomical reference for this species is still missing. Here we present the first three-dimensional, multimodal atlas of the Monodelphis opossum brain.

The expression of interleukin-6 and its receptor in various brain regions and their roles in exploratory behavior and stress responses.

We examined the involvement of interleukin-6 (IL-6) and its receptor IL-6Rα on behavior and stress responses in mice. In the open field, both wild-type (WT) and IL-6 deficient mice displayed similar levels of locomotor activity; however, IL-6 deficient mice spent more time in the central part of the arena compared to control WT mice. After behavioral testing, mice were subjected to stress and then sacrificed.

3D brain atlas reconstructor service--online repository of three-dimensional models of brain structures.

Brain atlases are important tools of neuroscience. Traditionally prepared in paper book format, more and more commonly they take digital form which extends their utility. To simplify work with different atlases, to lay the ground for developing universal tools which could abstract from the origin of the atlas, efforts are being made to provide common interfaces to these atlases.

Lipopolysaccharide injected to pregnant mice affects behavior of their offspring in adulthood.

We studied consequences of maternal immune response on the course of pregnancy and the behavior of adult offspring. Mice in late gestation (day 16-17) were injected with lipopolysaccharide (LPS). Treatment of pregnant mice with high doses of LPS resulted in fetal resorption or stillbirths.
