Gut bacteria influence autism-like behaviors in mice

Using germ-free mouse models, researchers transplanted fecal bacteria from children on the autism spectrum and neurotypical children. Mice who received the transplants from the ASD cohort began to exhibit autism-like behaviors, whereas the mice who received transplants from typically developing children did not. Additionally, the mice showed altered gene expression in their brains and differences in types of metabolites present. In particular, the ASD mice had lower levels of 5AV and taurine. Findings suggest gut microbiota regulates autism-like behaviors via the production of neuroactive metabolites, providing further evidence for the gut-brain axis connection to the pathology of autism....

Seeing disfigured faces prompts negative brain and behavior responses

Neuroimaging reveals people experience a diminished neural response in the anterior cingulate cortex when shown images of others with facial disfigurements. A similar response is also seen when people view other stigmatized people, such as those who are homeless. The diminished activity may explain why people are less empathetic toward those who have facial disfigurements and may help explain the underlying neural mechanism for dehumanization. ... Read More...
