How Parietal Cortex Orchestrates Brain Network Flexibility: A Triple Configuration Model
A new study identifies the parietal network as a hub that flexibly configures brain networks in response to external stimuli, tasks, and spontaneous activity, offering insights into cognitive flexibility.
AI Spots ADHD Risk Years Before Diagnosis by Mining Health Records
New research shows AI can analyze routine electronic health records to estimate a child's risk of ADHD by age 5, years before typical diagnosis.
Baby Brains Start Full: Why Memory Networks Prune Instead of Grow
New research shows the hippocampus begins with a dense, random network that gets streamlined over time—challenging the idea that we learn by adding connections.
How Attention Simplifies Mental Maps for Better Planning
Spatial attention acts like a spotlight, selectively simplifying which parts of a task enter awareness and boosting planning efficiency.
Language and Empathy Develop from Separate Brain Systems, Study Finds
New fMRI research shows that children's brains have distinct, non-overlapping regions for language and theory of mind from as early as age 3, challenging theories that these skills emerge from a shared cognitive source.
Potassium ions act as a brain receptor switch, new study finds
A serendipitous discovery reveals that potassium ions act as ligands for brain receptors in fruit flies and humans, offering new insights into epilepsy and brain homeostasis.
New Theory Quantifies Information Stored in Synapses
Researchers developed a framework to measure information stored in synaptic connections, revealing synergy where the whole exceeds the sum of its parts.
A New Framework Clarifies What 'Representation' Really Means in Neuroscience
Researchers propose a unified conceptual framework with four dimensions—sensitivity, specificity, invariance, and functionality—to clarify how brain activity represents sensory information.
Ultra-Processed Foods Linked to Decline in Visual Attention and Processing Speed
New research finds that even a small daily increase in ultra-processed foods can measurably reduce visual attention and processing speed, independent of overall diet quality.
Liver Hormone FGF21 Communicates with the Brain to Control Appetite and Metabolism
Researchers discovered that a liver hormone called FGF21 activates hindbrain neurons to regulate appetite and energy use in response to low dietary protein.
New framework RE-CONFIRM assesses reliability of brain biomarkers from fMRI
A new framework called RE-CONFIRM evaluates whether deep learning models identify robust biomarkers from brain scans, revealing that fine-tuning foundation models can miss key brain hubs.
EEG reveals early brain preconfiguration failure as marker of repetitive subconcussion
New EEG study shows that millisecond-level cortical preconfiguration dynamics can distinguish repetitive subconcussive brain injury from healthy controls with high accuracy.
