Quitting Smoking Slashes Dementia Risk 16%, but Weight Gain Over 22 Pounds Erases Benefits
A 10-year study finds that quitting smoking lowers dementia risk by 16%, but gaining 22+ pounds afterward cancels the benefit. Weight maintenance is key.
Zero-Shot Decoding of Handwriting from Brain Activity Achieves 64% Accuracy
Researchers achieve 64% hits@3 in decoding unseen handwritten characters from neural activity, suggesting motor cortex uses shared kinematic primitives.
How Action-Focused AI Models Mirror Your Brain During Gameplay
Vision-language and action models align differently with human brain activity during gameplay, with action-specialized models reorganizing representations toward motor-planning regions.
Playing Rock-Paper-Scissors With a Human Makes You More Random
New study shows that facing a human opponent can make your moves more unpredictable than facing a random generator, suggesting randomness is socially shaped.
Context Changes How Your Brain Represents Objects: Study
Objects activate different brain networks depending on whether they are passive or action targets, reshaping how they are represented.
Sparse Autoencoders Reveal How LLMs Mirror Brain's Semantic Map
New research shows that sparse autoencoders can extract semantic features from LLMs that map onto the brain's cortical semantic topography, explaining why intermediate LLM layers best predict brain responses.
Neutrophils Produce Schizophrenia Risk Protein C4A, Study Finds
White blood cells called neutrophils act as hidden factories for C4A, the strongest common genetic risk protein for schizophrenia, driving excessive synaptic pruning.
Adult Brain Recycles Prenatal Genetic Playbook for Memory
New research shows adult neuroplasticity reuses the same molecular toolkit from embryonic development, revealing a shared genetic playbook for learning and memory.
Scientists Discover Brain Region Behind Abstract Thought and Creativity
New research pinpoints the ventral premotor cortex as the neural engine for recombining familiar symbols into novel ideas, revealing how your brain thinks creatively.
Synaptic Efficiency Explained by Information Theory
New research from James Stone shows synapses naturally operate at signal-to-noise ratios that maximize bits per joule, explaining why efficiency drops when conductance deviates.
AI Passes Turing Test: What It Means for Human Cognition
In a first, a large language model convinced people it was human 73% of the time. This milestone reveals how AI mimics personality and what it tells us about our own minds.
Mathematical Model Reveals How Temporal Interference Stimulation Activates Neurons
Researchers used math and simulations to show how two intersecting electrical fields can trigger or silence a single neuron, depending on amplitude and beat frequency.
