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.
New AI Method Reveals How Brain Areas Control Each Other
MIT researchers developed JacobianODE, a deep learning method that estimates how brain areas exert control over each other, revealing that sensory regions gain more influence over cognitive areas during learning.
Alzheimer’s Drugs That Clear Amyloid May Not Help—and Raise Brain Risks
A major Cochrane review of over 20,000 participants finds anti-amyloid drugs offer no meaningful benefit for Alzheimer’s and may increase the risk of brain swelling or bleeding.
Tightening Your Abs May Trigger a Brain-Cleaning Effect
New research reveals that contracting your abdominal muscles pushes fluid through the brain, potentially flushing out waste. Just moving your body might quietly 'rinse' your brain.
Blocking a Single Protein Restores Memory in Alzheimer's Mice
Researchers found that blocking the protein PTP1B improved memory and cleared amyloid plaques in Alzheimer's mice by boosting microglial function.
Agentic Behavioral Modeling: Bridging AI and Human Cognition
New research from Ostwald et al. introduces agentic behavioral modeling (ABM), a framework that treats AI agents as latent hypotheses about cognitive mechanisms to explain human behavior.
Reverse Engineering Ketamine: A Safer Route to Rapid Antidepressant Effects
By identifying specific opioid receptors and receptor cross-talk, researchers replicated ketamine's benefits using a safer triple-drug combination in mice.
Boosting Sox9 Protein Helps Astrocytes Clear Alzheimer's Plaques
Scientists at Baylor College of Medicine discovered that increasing the protein Sox9 activates astrocytes to clear amyloid plaques, preserving memory in mice with Alzheimer's symptoms.
