Why the study?
Does dual-task challenge affect prefrontal cortex activation differently in younger versus older adults?
Does dual-task challenge affect prefrontal cortex activation differently in younger versus older adults?
High cognitive load from dual-task activity increases prefrontal cortex activity in older adults, particularly those with better baseline attention and executive functions.
No takes yet. Share an insight, caveat, or question.
Age-specific PFC recruitment during dual-task may reflect compensation; leaves open whether it predicts decline or guides interventions.
Ohsugi et al. (2013) studied this question.
