Predictive Brain: Why Categorization is an Action, Not an Idea

A landmark paper argues that the brain categorizes the world based on action plans rather than sensory prototypes. This predictive approach allows the brain to meet the body's needs efficiently.

How the Brain Maps What vs. Where When Reality Shifts

The hippocampus reorganizes its activity based on expectations. The anterior region processes "what" changes (objects), while the posterior region handles "where" changes (location).

Edge of Chaos: Why Pigeons Refuse to Become “Machines”

Researchers found that pigeons rewarded for any behavior sequence still refuse to settle on a single "best" path. This "edge of chaos" behavior suggests a deep-seated biological need for flexibility over efficiency.

Neurons Lose Their “Adaptability” in Old Age

Researchers are developing a multiscale "neurometabolic" model to track how the brain's energy consumption drives aging and Alzheimer's. The $3.3M project aims to identify metabolic warning signs years before cognitive decline begins.

High IQ and High Status Share the Same Genes

A new study reveals that genetics explain up to 98% of the correlation between IQ and socioeconomic status. Researchers found that while upbringing matters, innate intelligence—driven largely by heredity—is the primary predictor of adult success.

Mentally Active Leisure Protects Against Dementia

A 19-year study reveals that mentally active sitting—such as reading or working—can reduce dementia risk, while passive sitting like watching TV increases it. Researchers suggest "swapping" passive habits for active ones to protect long-term brain health.

AI “Creativity” is More Predictable Than Human Thought

New research shows that while AI can produce "creative" answers, its outputs are far more repetitive and predictable than human thought. Relying on LLMs for brainstorming may unintentionally limit the diversity of human ideas.

COVID-19’s Stalling Effect on Children’s Executive Function

The COVID-19 pandemic significantly stunted the growth of children's executive function skills regardless of family income. This delay in self-control and attention development may be a primary driver of post-pandemic academic and behavioral struggles.

Blood Test Predicts Long-Term Cognitive Function After Cardiac Arrest

A new study reveals that neurofilament light chain (NfL) is a superior biomarker for predicting cognitive function after cardiac arrest. Learn how this 48-hour blood test outperforms current methods in identifying long-term brain injury risk.
