New Neuroplasticity Mechanism: How a Single Experience Can Rewire Your Brain
Researchers discovered a new form of neuroplasticity called BTSP that can rewire brain circuits after one experience, explaining fast learning.
Synaesthesia: When Senses Mix, and What It Reveals About Your Brain
Synaesthesia, affecting 1-4% of people, causes senses to blend—like seeing colors in music. Research reveals extra brain connections, offering insight into diverse perception.
Why Positive Reinforcement Can Trap Ideas in a 'Death Spiral'
New research shows that Hebbian learning — 'neurons that fire together, wire together' — can actually trap ideas in feedback loops, while weakening connections allows for wider spread.
Alzheimer's Defense: Unexpected Microglia Subtype Protects Brain, New Atlas Shows
Mapping over 830,000 brain immune cells reveals a protective microglia subtype that expands in Alzheimer’s, clearing harmful material via TREM2, offering new drug targets.
Reading Cognition as Decisions Unfold in Words: Factorized Inverse Decision Model
Researchers introduce a factorized inverse decision model (FIDM) to analyze verbal task dynamics, improving cognitive screening and classification beyond action-based methods.
How LLMs Reorganize Brain-Like Representations During In-Context Learning
New research shows large language models reshape their internal geometry to better separate categories during in-context learning, revealing why some tasks are easier to learn from examples.
FedDOSE: A New Federated Learning Framework for Brain Imaging Analysis
Researchers developed FedDOSE, a federated learning framework that improves diagnosis of autism and ADHD by analyzing dynamic brain connectivity while preserving privacy across multiple sites.
Human Reading vs. AI: Where Eye Tracking Shows the Divide
A new study compares human eye-tracking to 400+ LLMs, revealing where AI fails to explain human rereading and text integration.
Large Language Models Mimic Human Brain During Creative Thinking
New research reveals that large language models align with brain activity during creative tasks, with larger models and those optimized for creativity showing stronger alignment.
Brain's Immune System Overhaul Begins at 50, New Study Shows
Around age 50, the brain's memory center swaps its resident immune cells for more inflammatory ones, a shift that may explain how aging primes the brain for Alzheimer's and dementia.
Your Brain's 'Executive' Can Block Creative Problem-Solving
New research reveals that the medial prefrontal cortex, often seen as the brain's manager, can actually hinder creative thinking by sticking to old habits. Silencing it helps mice learn faster.
Early Stress Leaves Physical Scar on Brain's Dopamine Neurons
Childhood trauma raises the enzyme SETD7 in dopamine neurons, uncoiling DNA and making adults more vulnerable to stress and anxiety.
