  "textContent": "Studying cognition by averaging data from many people's brain scans hides how individuals use their brains, new Stanford Medicine research has shown. In particular, children who struggle with goal-oriented tasks show distinct patterns of brain activity when their data is analyzed individually, rather than as part of a group of kids with mixed abilities. The findings, which have implications for understanding how the brain works in such conditions as attention-deficit/hyperactivity disorder, will be published April 27 in Nature Communications.",
