Poor Early Diet Linked to Lower IQ in Adolescence, Study Finds
A review of 73 studies finds sub-optimal nutrition in infancy correlates with lower intelligence scores in adolescence, highlighting the need for early dietary interventions.
Irregular Sleep Hurts Kids’ Vocabulary and Memory, Study Finds
A new study shows that irregular sleep patterns lower receptive vocabulary and visuospatial memory scores in preschool children, independent of total sleep duration.
AI Council Maps Brain's Predictive Coding Hypotheses with Geometry
A team used ten language models to score 31 studies on predictive coding, revealing structured disagreement and a new metric called hypothesis-space temperature.
Irregular Sleep Patterns Linked to Brain Tissue Damage in Large Study
A study of 23,000 adults found that short sleep, frequent napping, and sleeplessness are linked to increased white matter lesions, a marker of brain aging.
Brain Signals Boost LLM Reasoning: A Step Toward Cognitively Aligned AI
New research shows that brain activity from reasoning tasks can directly enhance large language model performance, yielding up to 13% accuracy gains across 10 models.
Reverse Autism Brain Defects: Circuit-Specific Fix Restores Neuron Function
New study shows structural autism deficits in brain cells are reversible. Targeted chemogenetic activation restored neuron firing and improved social behavior in mice.
Why Teen Cannabis Use May Disrupt Brain Dopamine Development
Adolescents who use cannabis, especially high-potency products, show reduced brain iron levels in dopamine regions, indicating disrupted reward system maturation.
New Cognitive Field Theory Shows Learning & Memory Emerge from Infrared Dynamics
A new theory models cognition as a collective nonequilibrium phenomenon, revealing that learning and memory arise from slowly relaxing 'infrared' modes in a high-dimensional cognitive manifold.
True Multitasking is Possible: How Your Brain Rewires Itself to Automate Skills
New research from Georgetown University shows that with extensive training, the brain can physically move automated tasks from the prefrontal cortex to the temporal cortex, enabling true parallel processing.
Motor Cortex Bursts Code for Goals, Not Just Actions
New research shows that bursts of neural spikes in motor cortex encode goal information separately from action, enabling rapid adaptation.
Third-Order Brain Statistics Predict Cognition Better Than Billion-Parameter AI Models
New research shows that third-order statistics (co-skewness) in fMRI predict cognitive performance better than large brain foundation models, challenging current AI approaches.
Neural competition as a game: new theory of brain dynamics
Researchers show that excitatory-inhibitory neural networks behave like a competitive game, with each neuron minimizing its own energy. This bridges game theory and neuroscience.
