Whole-brain activity assessed by functional MRI indicates that the performance of motor control tasks is prioritized over cognitive performance when both are carried out together.
The left Brodmann area (BA) 5, right BA6 and left caudate are linked to dual-task performance
Why this matters
Current knowledge of how humans resolve dual-task interference is limited – these findings are the first to show that cognitive performance decreases in favor of motor control.
Additional research into ankle motor control during cognitive challenges may help reduce dual-task-related falls in an aging or clinical population.
