Neural Code Stability Predicts Behavior Better Than Drift
A new study shows that how reliably neural patterns maintain their geometric relationships predicts trial-by-trial behavior, while centroid drift does not.
Brain Protein Arc Spreads Toxic Tau in Alzheimer’s, New Study Finds
A new study identifies the brain protein Arc as the key carrier that spreads toxic Tau between neurons in Alzheimer’s disease, opening a potential target for stopping progression.
Global study maps how culture shapes self-control and delayed gratification
A massive 77-nation study with ~15,000 participants reveals how cultural and situational factors influence our ability to delay gratification, with key implications for personal finance, health, and sustainability.
Why MS Progresses Differently: Brain Tissue Patterns Tied to Genetics
A landmark study of 287 brain donors shows that MS severity is driven by four distinct tissue patterns—genetically influenced—opening the door to personalized treatment.
Two Weeks of Adolescent Social Isolation Permanently Destroys Adult Empathy
A brief two-week social isolation during adolescence permanently destroys the ability to sense peer distress, even after re-socialization, while adult isolation leaves emotional discrimination intact.
Nanosensor Differentiates Autism from Intellectual Disability Using Stem Cells
A carbon-fiber nanosensor measured nitric oxide in stem cells to distinguish Autism Spectrum Disorder from Intellectual Disability, even with identical genetic mutations.
Viral Infection Triggers Parkinson's Brain Damage in New Study
A new study shows a common virus can trigger the exact dopamine neuron loss and motor deficits seen in Parkinson’s, offering a natural model for the disease.
Chronic Stress Stiffens Brain Networks: Trade-Off Between Resilience and Flexibility
New research on arXiv models chronic stress in working-memory networks, finding that resilience training preserves performance but reduces generalization ability.
Does expressive style affect brain's speech tracking in cognitive decline?
New research shows that subjective cognitive decline (SCD) is linked to weaker cortical tracking of linguistic features, especially during flat speech, suggesting a new early neural marker.
Reading Rewires Your Brain: Enhances Memory, Face Recognition, and Reasoning
New research shows reading fine-tunes visual systems, improves face recognition, expands working memory, and sharpens reasoning. Print reading beats screens for cognitive effort.
Fish Oil Supplements Fail to Boost Memory or Slow Brain Aging in Landmark Study
A two-year clinical trial found that high-dose omega-3 fish oil supplements did not improve memory, cognition, or protect against Alzheimer's-related brain changes, despite successfully raising brain omega-3 levels.
VR and Nerve Stimulation Doubles Stroke Arm Recovery in New Study
Combining immersive VR with electrical nerve stimulation doubles upper limb recovery in chronic stroke patients by reconnecting movement and touch sensation.
