Researchers say people continue to process music, even when no songs are playing. This can lead to earworms, or tunes that get stuck in your head, which can crop up during sleep. People who experience earworms regularly at night are six times more likely to report poorer quality sleep.
Researchers have identified a subpopulation of dopaminergic neurons in the caudal ventral tegmental area that appears to suppress food intake by triggering satiation in mice.
A new computational model can identify genes linked to autism and predict the level of intellectual disability in people with ASD by only using rare mutations in genes already associated with the condition.
When necrotic cells expose phosphatidylserine on their outer surfaces, and when phagocytes detect it, the phagocytes ingest and destroy the dying cells.
Intermittent fasting can help to reduce hypertension by reshaping the gut's microbiome.
Mice that consumed high-fat diets not only became obese, they also displayed an increased risk of depression and anxiety symptoms. This was mediated by a defective brain circuit. When the disruptions were corrected either genetically or pharmaceutically, mice displayed fewer symptoms of depression and experienced weight loss.
In mouse models of neurodevelopmental disorders, researchers found social deficits were mediated by microbes in the gut. By contrast, hyperactivity is controlled by genetics. Treatment with a specific microbe helped improve social behavior.
Study provides the most detailed and complete characterization of diversity in neural types in the brain to date.
Researchers have identified a group of glucose-sensing neurons in the ventrolateral area of the ventromedial hypothalamic nucleus and discovered how they work together to prevent hypoglycemia in mice.
Smoking remodels the gene expression of lung cells so that the ACE2 gene is more highly expressed in goblet cells. The effects of smoking on ACE2 pulmonary expression indicates an increase in the overall entry points for coronavirus and increases the risk for viral binding and entry of COVID-19 into the lungs.
