To test the possible relationship between the gut and chemo brain, Leah Pyter's lab is examining chemo's effects on mice whose guts have been manipulated before treatment. One experiment involves feeding the mice antibiotics. The other relies on the universal practice among mice of eating their own and their roommates' feces.

Experimental advances using lab-grown brain organoids are helping to clarify how best to use them as a model system to understand human brain development and diseases. The findings were presented at Neuroscience 2019, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health.

New research makes advances in understanding how smells are perceived and represented in the brain. The findings were presented at Neuroscience 2019, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health.

Advances in the study of human social behavior may lead to a better understanding of normal processes such as empathy and theory of mind, as well as dysregulated conditions including autism spectrum disorder. The findings were presented at Neuroscience 2019, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health.

Neuroscientists say they have developed and tested an agent that reduces the buildup of toxic proteins in animal models of both Parkinson's and Alzheimer's diseases, and improves cognitive and motor behavior.

Human-made toxic chemicals that linger indefinitely in the environment disrupt the performance of critical helper cells in the mouse brain, leading to impaired function over long-term exposures.

Advances in the study of cognitive disorders, including Autism Spectrum Disorder (ASD), may pave the way for future treatments. The findings were presented at Neuroscience 2019, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health.

Chronic stress during pregnancy triggers an immune response in the brain that has potential to alter brain functions in ways that could contribute to postpartum depression, new research in animals suggests.
