Brain Signal Linked to OCD Compulsions Identified
Summary: Researchers have identified a specific pattern of high-frequency brain activity in the anteromedial orbitofrontal cortex (amOFC) that is consistently linked to compulsive behaviors in people with obsessive-compulsive disorder (OCD).…
Multilingualism Calculator Reveals True Language Strengths
Summary: A new study introduces a multilingualism calculator that quantifies how multilingual a person truly is, offering a clearer alternative to vague labels like “bilingual.” By combining age of acquisition…
Brain Blends Fast and Slow Signals to Shape Human Thought
Summary: Researchers mapped the brain connectivity of 960 individuals to uncover how fast and slow neural processes unite to support complex behavior. They found that intrinsic neural timescales—each region’s characteristic…
Immune Signal Ratio May Predict Progressive Multiple Sclerosis
Summary: A long-term study has identified a potential biomarker that could help detect which patients are progressing toward more severe forms of multiple sclerosis. Researchers discovered that a high ratio…
Early Screen Time Linked to Long-Term Brain Changes, Teen Anxiety
Summary: New research following children for more than a decade links high screen exposure before age two to accelerated brain maturation, slower decision-making, and increased anxiety by adolescence. Infants with…
Missing Brain Receptor May Hold the Key to Autism
Summary: Autistic adults show reduced availability of a key glutamate receptor, mGlu5, across widespread brain regions. This difference supports the theory that an imbalance between excitatory and inhibitory signaling may…
Is Your Oral Bacteria Influencing Multiple Sclerosis?
Summary: High levels of the periodontal bacterium Fusobacterium nucleatum may be associated with more severe disability in people with multiple sclerosis. Researchers analyzed tongue-coating samples and found that MS patients…
Stroke Weakens How the Brain Integrates Speech Sounds
Summary: A new study comparing stroke survivors with healthy adults reveals that post-stroke language disorders stem not from slower hearing but from weaker integration of speech sounds. While patients detected…
