Summary: A massive observational study of more than 277,000 adults reveals that loneliness and social isolation significantly shorten disease-free life expectancy, stripping men of nearly six years and women of…

Inflexible Math Brain: How Neural Circuit Glitches Block Problem Solving
Summary: Stanford University researchers analyzing brain activity and behavioral metrics in 8- to 10-year-olds found that children with developmental dyscalculia struggle to switch between and optimize math problem-solving strategies. Distinct…
Nighttime Light Exposure Linked to Sleep Loss in Schizophrenia
Summary: A new study reveals that nighttime light exposure is strongly associated with objective sleep disruption in outpatients with schizophrenia, resulting in nearly an hour less total sleep per night.…
Eye-Blink Rate Predicts Cognitive Flexibility in Preschoolers
Summary: Researchers have discovered that spontaneous eye-blink rate serves as a simple, noninvasive marker for tracking the development of executive function in early childhood. The study revealed that children aged…
Disruption of Striatal D2 Receptor Neurons Drives ADHD and Impulsivity
Summary: Researchers have demonstrated that deleting the membrane-fusion protein NSF specifically from dopamine D2 receptor (D2R)-expressing neurons leads to striatal shrinkage, severe dopamine depletion, and classic ADHD-like hyperactivity and impulsivity…
Brain Activity Predicts Risky Choices Half a Second Before They Are Made
Summary: By recording directly from electrodes implanted in the human orbitofrontal cortex, neuroscientists discovered two neighboring circuits locked in a millisecond-by-millisecond “tug-of-war” between taking a risk and playing it safe.…
Aging Brains Maintain Robust Language Networks Despite Cognitive Decline
Summary: While executive functions like memory and problem-solving naturally decline as we age, new brain imaging research reveals that the neural network responsible for language remains preserved and fully functional.…
Shame, Stigma, and Culture Prevent Male Domestic Violence Survivors From Seeking Help
Summary: A new large-scale study identifies the primary barriers that prevent male victims of intimate partner violence (IPV) from seeking help. Researchers found that viewing the abuse as a private…
Dog Brains Differentiate Human Anger, Fear, and Sadness
Summary: A new study demonstrated that dogs possess specialized neural networks for processing human facial expressions. The team used functional magnetic resonance imaging (fMRI) and machine learning to analyze canine…
Why Psychedelics Make Everything Feel Deeply Connected
Summary: Researchers introduce “apical hypercontextualisation”—a bottom-up neurobiological mechanism explaining how psychedelics (psilocybin, LSD, DMT, mescaline) transform perception and cognition. Moving beyond macro-scale whole-brain neuroimaging, the framework focuses on the cellular…
