Avoiding the fall: ankle motor control versus cognitive performance during dual tasks

Takeaway

  • 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.
