Scientists at The Ohio State University have charted how patterns of brain wiring can predict activity linked to many mental functions across the entire brain. Each region shows a distinct “connectivity fingerprint” tied to roles such as language and memory. The peer‑reviewed findings in Network Neuroscience offer a baseline for studying healthy young adult brains and for comparisons with neurological or psychiatric conditions.
Researchers at Rutgers Health have identified how the brain integrates fast and slow processing through white matter connections, influencing cognitive abilities. Published in Nature Communications, the study analyzed data from nearly 1,000 people to map these neural timescales. Variations in this system may explain differences in thinking efficiency and hold promise for mental health research.

Researchers at Concordia University have discovered that people blink less when concentrating on speech amid background noise, highlighting a link between eye behavior and cognitive effort. This pattern persists regardless of lighting conditions, suggesting it's driven by mental demands rather than visual factors. The findings, published in Trends in Hearing, could offer a simple way to measure brain function during listening tasks.
