Description
Wan-Chun Su and co-authors check whether brain and behavior measures hold steady across posture shifts. Their 2026 paper uses light-based brain imaging during a dual task: keeping balance while holding back wrong answers. Eighteen healthy adults sat, stood, and stood heel-to-toe, with tasks of rising difficulty. Scans were repeated after a sit-to-stand bout.
At low loads, brain activity rose with task demand in frontal and sensor zones. At high loads, the pattern flipped. Behavior scores ranged from shaky to rock steady on repeat. Brain measures were less steady still after posture change. The authors read the load flip as shared mental resources running dry. They warn studies to log posture when reading such data.
