Our brains contain around 100 billion neurons communicating through an intricate web of connections. This complex circuitry controls everything we think, feel, and do. But sometimes things can go wrong, leading to neurological disorders like epilepsy, Parkinson’s disease, depression and Alzheimer’s. An exciting new approach called transcranial ultrasound stimulation (TUS) is showing great promise as …
Focused ultrasound (FUS) is an exciting noninvasive brain treatment technology that is revolutionizing how we approach neurological and psychiatric diseases. This incisionless technique uses precisely targeted sound waves to therapeutically stimulate or ablate brain tissue. The Big Picture: FUS uses focused, high-intensity sound waves to precisely treat diseased brain regions without incisions. It has FDA …
The FDA-approved diabetes drug semaglutide reduces alcohol drinking in mice and rats, suggesting it could be repurposed as an effective medication for alcohol use disorder (AUD). Key findings include: Semaglutide dose-dependently decreased binge-like drinking in both male and female mice. In rats, semaglutide reduced binge-like and dependence-induced alcohol drinking. Semaglutide also decreased consumption of caloric …
Autism spectrum disorder (ASD) is a complex condition characterized by challenges in social communication and repetitive behaviors. One aspect that contributes to the heterogeneity seen across the autism spectrum is differences in intelligence and cognitive abilities.

Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by social communication deficits and repetitive behaviors. The causes are complex, involving genetic and environmental factors that affect brain development. Growing evidence implicates immune system abnormalities and neuroinflammation in ASD. Galectin-1 and galectin-3 are proteins that regulate immune responses and inflammation. A new study found significantly …
A new case-control study reveals an association between obesity, depression, and decreased levels of the protein neuregulin-1 (NRG-1). The research suggests NRG-1 may serve as a biomarker linking depression and obesity. Key facts: Depressive symptoms were more common in obese individuals compared to normal weight controls. After bariatric surgery, most obese patients saw an improvement …
