Why Past Trauma Amplifies Future Stress

Summary: Researchers at the Icahn School of Medicine at Mount Sinai have uncovered an overlooked neural circuit in the anterior hypothalamic nucleus (AHN) that dictates how past trauma primes the…

Making Music May Rewire the Addicted Brain

Summary: A pilot neuroimaging study from Anglia Ruskin University reveals that music therapy directly modulates brain wave dynamics linked to emotional regulation and craving suppression in individuals recovering from drug…

Mitochondria in the Brain’s Reward Hub Drive Nicotine Dependence

Summary: Supported by a $943,000 NIH grant, neuroscientists at the University of Central Florida are investigating how nicotine alters neuronal mitochondria within the nucleus accumbens. By examining the subcellular mechanisms…

Chronic Stress Shapes Cognitive Aging

Summary: A longitudinal study of nearly 3,900 older adults revealed that while robust social support helps shield attention from age-related decline across all demographics, it does not counteract the harmful…

Loneliness Erases Nearly 6 Healthy Years

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…

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…

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.…

Eye Tracking Reveals Where Human Reading and AI Processing Diverge

Summary: A new study evaluated whether large language models (LLMs) can accurately account for human reading dynamics. The team compared eye-tracking data from 368 adult readers against predictions generated by…

Prefrontal Cortex Can Block Creative Problem-Solving

Summary: Researchers discovered an unexpected role for the medial prefrontal cortex (mPFC), a region traditionally viewed as the executive driver of behavioral flexibility. The team demonstrated that the mPFC can…

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…
