GLP-1 Drugs Rewire Brain’s Reward System to Reduce Cravings
New research reveals that GLP-1 weight-loss drugs directly alter brain circuits controlling motivation and reward, reducing desire for high-calorie foods by acting on dopamine pathways.
Brain Performance Can Improve at Any Age, Landmark Study Shows
A three-year study of nearly 4,000 adults aged 19-94 found that consistent cognitive micro-training boosts brain performance at any age, challenging the myth of inevitable decline.
Learning Exposes Hidden Structure in Neural Networks
New research reveals that learning can uncover invisible differences in neural networks and that training history is stored in hidden connectivity.
New theory ties consciousness to a single brain agent checking internal models during saccades
A new theory proposes consciousness arises from a 'Modelerschema' that monitors the brain's internal model-building and performs qualia checks during saccades. A falsifiable experiment is proposed to test it.
Why Regret Loses Its Sting as We Age: New Research on Emotional Resilience
A new study finds that older adults experience less anger and frustration when reflecting on regrets, shifting from distress to meaning-making.
Magnetic Pulses Restore Lost Brain Connections in Depression
Accelerated TMS repairs dendritic spines on specific neurons within 24 hours, providing the first cellular evidence of how the therapy works.
Tri-Modal AI Predicts Brain Activity Better Than Traditional Models
TRIBE v2, a tri-modal AI model using video, audio, and language, predicts fMRI brain activity with several-fold higher accuracy than linear encoding models.
Neural Alignment Boosts AI Robustness, but Not via Spatial Frequencies
New research dissociates spatial frequency reliance from adversarial robustness in neural network models, revealing that human-like representations, not low-frequency bias, drive resilience.
Think-Aloud Data Improves AI-Generated Cognitive Models of Decision-Making
Adding think-aloud verbal data to AI-driven cognitive modeling leads to more accurate and structurally different models of risky decision-making, researchers find.
Everyday Computer Use Reveals Mental Health with Biomarker Accuracy
New MAILA framework analyzes mouse and touchscreen movements to track mental health—across 13 dimensions—with near-perfect group accuracy.
Adult Brain Holds Millions of Silent Synapses Ready for Learning
MIT neuroscientists discovered that about 30% of synapses in the adult cortex are 'silent'—immature connections that can be rapidly activated to form new memories without overwriting old ones.
Fluoride in US drinking water and IQ: No evidence of harm
A new study of over 10,000 Wisconsin teens found no link between fluoridated water and lower IQ or cognitive ability, challenging recent policy moves.
