Alzheimer’s and Parkinson’s Share a Brain Signature, MRI Study Shows
New MRI research maps a common grey‑matter pattern in Alzheimer’s and Parkinson’s, with thinning in the putamen and accumbens linked to both diseases.
AI Decodes Pain from EEG, Maps Delta Brainwaves for Objective Tracking
A new AI platform analyzes EEG signals to objectively classify pain intensity, isolating delta wave activity at F7 and F8 nodes, avoiding subjective bias.
Cortex Learns General Structure, Subcortex Handles Rewards When Memory Is Limited
New research formalizes how the brain splits learning: the cortex focuses on general structure, while subcortical circuits handle reward learning, especially when memory is limited.
DBS Physically Rewires Brain Pathways to Reverse Depression, Mount Sinai Study Finds
Mount Sinai researchers directly show for the first time that deep brain stimulation physically remodels white matter and rewires neural networks, explaining how it reverses severe depression.
Whole-Brain State Predicts Social Approach Seconds Before Action
A new study reveals a distributed brain-wide signature that emerges seconds before social approach, predicting action and individual social drive.
Protein Traffic Jams in Aging Brains: New Clues to Memory Loss and Alzheimer's
Stanford scientists discovered that ribosome 'traffic jams' in aging brains cause faulty proteins and clumps linked to Alzheimer's, offering a new explanation for cognitive decline.
Optimal Ambition: Why Setting Goals Just Above Average Beats Perfectionism
A new mathematical model shows optimal ambition is strictly above average but finite—perfectionism costs far more than settling for less.
Supervised Training Rapidly Degrades Visual Cortex Alignment in Neural Networks
A new study shows that training neural networks with backpropagation reduces their similarity to early visual cortex by up to 90% after just one epoch, while local learning rules preserve brain-like structure.
