Rutgers Health Study Links Brain Connectivity to Cognitive Speed
A new study conducted by Rutgers Health and published in Nature Communications reveals how the human brain integrates fast and slow information processing through white matter communication networks. The research, which analyzed multimodal brain imaging data from 960 participants, focuses on intrinsic neural timescales (INTs) and their role in cognition and behavior. The findings indicate that the organization of these neural timescales across the cortex significantly influences the efficiency of transitioning between large-scale activity patterns. Individuals whose brain connectivity better aligns with regional processing speeds for fast and slow information demonstrate stronger cognitive abilities. The study also identified connections between these timing patterns and the genetic, molecular, and cellular properties of brain regions, with similar mechanisms observed in mice. Professor Linden Parkes emphasized that white matter connectivity is crucial for integrating information across different timescales to support behavior. The research team plans to extend this work to investigate neuropsychiatric conditions such as schizophrenia, bipolar disorder, and depression, aiming to explain how disruptions in brain connectivity affect information processing over time.
