Stanford Medicine study in Nature Communications finds individual-level fMRI analysis reveals brain-behavior patterns that group averages actively reverse.
Key Takeaways
Study analyzed 4,000+ children aged 9-10 from the ABCD dataset using fMRI during a stop-signal inhibitory control task.
Group averages showed slower reaction times correlating with increased default mode network activity; individual analysis showed the opposite.
Children split into adaptive vs. maladaptive regulation subgroups showed near-opposite brain dynamics, hidden when data was pooled.
Cognitive control has distinct sub-processes (proactive vs. reactive) orchestrated by different brain regions, not a single static capacity.
Findings have direct implications for ADHD and related conditions, suggesting multiple compensatory pathways exist for inhibitory control.
