Blood tests revealed specific epigenetic biomarkers for schizophrenia. Researchers applied machine learning to analyze the CoRSIVs region of the human genome to identify the schizophrenia biomarkers. Testing the model with an independent data set revealed the AI technology can detect schizophrenia with 80% accuracy.
The brain regulates both eating for hunger and pleasure through serotonin-producing neurons in the midbrain, but the different types of feeding are wired by independent circuits that do not influence the other type of feeding.
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.
