A newly invented soft, implantable probe can interface between gut and brain tissue, measuring both dopamine and serotonin levels. The device has applications for depression, Parkinson's disease, and intestinal disorders.
At age 13, teenagers no longer find their mother's voice uniquely rewarding, and tune into unfamiliar voices more. A new study reveals the neurobiology behind why teens begin to separate from their parents at this point of development and how it shapes them to become more socially adept outside a family setting.
A new AI algorithm can predict whether a person is on the autism spectrum by examining their brain scans. The algorithm can also predict the severity of symptoms and could be used as an early detection tool for ASD.
In children with autism, girls had different patterns of connectivity than boys in brain areas associated with motor, language, and visuospatial attention. Generally, girls display fewer repetitive behaviors than boys, which may contribute to delays in ASD diagnosis for females.
Around 25% of patients with multiple sclerosis have blood antibodies that bind to the Epstein-Barr virus and EBNA1, a protein made in the brain and spinal cord. Researchers say this is the first study to definitely show that the Epstein-Barr virus can cause multiple sclerosis in some patients.
Researchers discovered more than 1000 genes that are substantially more active in the brains of one sex versus the other. The findings may help behavioral sex differences in mammals.
Blood from young adult, fit mice benefits the brain of sedentary mice of the same age. A single protein, clusterin, appears to be largely responsible for the benefit.
SAINT, a new intensive and individualized form of transcranial magnetic stimulation reduces symptoms of depression within days of treatment. 80% of the people administered SAINT reported remission from depression symptoms that lasted for months following treatment.
Serotonin-producing neurons in the brainstem release serotonin throughout the brain during moments of novel social encounters. The release of serotonin stimulates neurons in the medial septum via a subtype of serotonin-sensitive receptor molecules. Blocking the release of this receptor molecule prevents the formation of new social memories.
Researchers propose a novel computational framework that uses artificial intelligence technology to disentangle the relationship between perception and memory in the human brain.
A diet rich in fermented foods, such as yogurt and kimchi, can help to improve gut microbiome diversity and reduce symptoms of chronic inflammation, a new study reports.
Recent studies have found significant biases in artificial intelligence algorithms. Researchers are raising their concerns about AI biases associated with medical devices and algorithms used to analyze health risks. If left unchecked, they say, the technologies could continue to perpetuate sex, gender, and race biases that could exacerbate health care disparities.
