News Finding: They could even see that the lags in connection development with the two task-related networks -- the frontoparietal and ventral attention networks -- were located primarily in two specific areas of the brain.
Paper Finding: These advances raise possibilities for investigating maturational lag in ADHD in the developing ICN architecture of the brain .
News Context: The researchers found lags in development of connection within the internally-focused network, called the default mode network or DMN, and in development of connections between DMN and two networks that process externally-focused tasks, often called task-positive networks, or TPNs. They could even see that the lags in connection development with the two task-related networks -- the frontoparietal and ventral attention networks -- were located primarily in two specific areas of the brain. The new findings mesh well with what other researchers have found by examining the physical structure of the brains of people with and without ADHD in other ways.
Paper Context: Our finding of maturational lag specifically in connections within and between these networks suggests a developmental etiology for the deficits proposed in these models. These advances raise possibilities for investigating maturational lag in ADHD in the developing ICN architecture of the brain . Thus, conventional seedbased strategies are likely to produce summary measures that do not capture underlying fine-grained patterns of variation or can miss trends that are detectable only when looking across large populations of connections.
