How Group Songwriting Resets the Brain's Prediction Systems in Psychosis
Yale researchers found that weekly group songwriting sessions reduced paranoia and increased social connection in people with psychosis by retraining the brain's predictive coding mechanisms.
Diverse Gut Bacteria Linked to Stronger Acute Stress Responses
A new study from the University of Vienna finds that higher gut microbial diversity is associated with stronger hormonal and subjective stress responses—a sign of flexible adaptation, not weakness.
When to Use AI for Critical Thinking: Timing Matters, Study Finds
A new study finds that using AI later in problem-solving boosts critical thinking and memory, while early use under time pressure trades reasoning for speed.
Why Humans Don't Regrow Brain Cells: The 'Bulldozer' Neuron Discovery
Zebra finches grow new neurons that tunnel through mature brain tissue, a finding that may explain why humans evolved to limit neurogenesis and protect existing memories.
Brain-Inspired Spiking Neural Network Uses Rhythmic Synchronization for Efficient Learning
Researchers propose S2-Net, an oscillatory spiking neural network that mimics brain rhythms and time-delayed synchronization for efficient learning across multiple cognitive tasks.
How Tiny Changes in Brain Networks Boost Cognitive Performance
New research reveals that small, sensitive parameter combinations in brain networks—not large variability—drive differences in working memory and attention.
Brain Tumor Surgery Risk Predicted by Neural Energy Landscapes
Pre-surgical fMRI energy landscapes predict postoperative working memory with 90% accuracy, offering hope for personalized surgery planning.
Echolocation: How Blind Experts Build Spatial Maps Click by Click
Brain accumulates spatial information with each mouth click, allowing expert echolocators to build a 3D mental map of their surroundings.
Simple Amino Acid Arginine Shows Promise Against Alzheimer's Damage
Researchers found that arginine, a low-cost amino acid, reduced toxic amyloid buildup and brain inflammation in animal models of Alzheimer's disease.
Near-Death Experiences May Be the Brain's Survival Reflex, Research Suggests
New research suggests near-death experiences are not hallucinations or glimpses of an afterlife, but an evolved survival mechanism that helps the brain cope with physiological collapse.
Brain-Body Resonance at 78 ms May Be Key to Conscious Unity
New EEG research shows a 78-ms brain-body resonance maintains self-organized criticality, enabling conscious integration. Removing physiological 'artifacts' destroys the effect.
Your Brain Doesn’t Start Blank—It Starts Full, Then Prunes for Efficiency
New research shows the brain’s memory center begins life densely connected, then becomes more efficient by pruning excess links—challenging the blank-slate idea.
