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.
Why Overconfidence Persists: The Costly Peacock Tail of the Mind
A new study explains that overconfidence survives evolution because its costly mistakes are a credible signal of ability, kept in check by loss aversion.
Teen Cannabis Use Linked to Slower Cognitive Development
New research from UC San Diego shows teens who use cannabis may develop memory, attention, and processing speed more slowly than peers, with THC as the likely culprit.
Exercise Shields Dopamine Neurons in Parkinson’s via Muscle ‘Exerkines’
A review of 129 studies shows exercise releases muscle-derived 'exerkines' that protect dopamine neurons and counter sarcopenia in Parkinson's disease.
ACh Receptor Density Shapes Brain-Wide Activity and Sleep Waves
A new brain model shows that regional differences in acetylcholine receptor density influence whole-brain activity and localized sleep waves, bridging molecular biology and network dynamics.
Base-Rate Neglect Isn't One Mistake—It's Two, and You Can Fix Both
New research shows we mishandle two separate base rates—the frequency of outcomes and cues—each with its own bias, offering a new path to improve decisions.
AI Explanations Reveal How Language Models Mirror Brain Activity
Explaining why large language models predict words also reveals how their computations align with brain activity during language processing.
Irrational Bias Persists Without Error Signals: New OSCAR Model Explains
A robust bias in category learning persists even without error feedback, challenging current theories. A new model, OSCAR, explains this across supervised, observational, and unsupervised learning.
How Brain Activity Patterns Change with Aging and Disease
New research shows that as we age, brain activity becomes more complex but less stable, while conditions like Alzheimer's lead to a collapse of both measures.
