Information Theory Explains Autism's Insistence on Sameness
A new information-theory framework proposes that insistence on sameness in autism reflects a drive to reduce surprise and uncertainty, with implications for learning therapies.
AI Decodes Brain Waves in Fragile X Syndrome via Alpha and Gamma EEG
A new hybrid deep learning model analyzes alpha and gamma brain waves to identify Fragile X Syndrome biomarkers, combining CNNs, LSTMs, and recurrence plots for better detection.
Ancient vs Modern PSPH Gene: How Human Brain Chemistry Evolved
Modern human PSPH gene variants produce L-serine more efficiently than ancient hunter-gatherer versions, a new yeast study reveals about brain evolution.
Hippocampus as Brain's Data Augmentation System, Study Finds
A new framework proposes the hippocampus works like data augmentation in machine learning—refactoring past experiences offline and online to fuel flexible, zero-shot generalization.
Your Brain's Weight Memory: Why Lost Pounds Come Back
Human brains evolved to defend body fat, treating your highest weight as the new normal. New research explains why dieting often fails despite willpower.
Orexin Neurons Drive Sustained Motivation, Study Finds
Nagoya University researchers show orexin neurons scale with effort and are necessary for goal-directed motivation, with implications for apathy and ADHD.
Upright Posture Boosts Risk-Taking and Pride, Study Finds
A McGill University study found that people subtly nudged into sitting upright took smarter risks and reported more pride — all without realizing their posture was being manipulated.
Brain Signals Reveal the Songs You Only Imagine
Seoul National University researchers decoded imagined melodies from intracranial brain signals in 10 epilepsy patients, reconstructing songs by tracking relative pitch classes like do, re, mi.
Cognitive Dark Matter: The Missing Ingredient in AI Intelligence
New research proposes "cognitive dark matter"—brain functions like metacognition and emotional intelligence that shape behavior but are missing from AI training and benchmarks.
16 Blood Molecules During Menopause Predict Alzheimer's Risk
UCSF researchers found 16 blood molecules that peak during menopause track with cognitive decline and a 15% higher Alzheimer's risk decades later.
Unexpected Free Time Makes Your Brain Feel It's Longer — And You Late
New research shows unexpectedly gained free time feels subjectively longer because of an expectancy violation, causing people to slow down, pick longer tasks, and still run late.
How Musical Improvisation Rewires Brain Activity
Improvisation quiets self-critical prefrontal areas and engages reward networks in both expert adults and children, revealing creativity as an innate brain function.
