Prefrontal activity

1. Age is associated with prefrontal activity in humans (β = 0.53, p = 0.04).

   “while OA had a relationship between age and prefrontal activity (β = 0.53, T = 2.33, p = 0.04).”

1. Stroop response time is associated with prefrontal activity in humans (β = 0.27, p = 0.01).

   “Stroop response time (β = 0.27, T = 3.10, p = 0.01) in PD, but not in OA.”

1. Dual-task cost of gait speed is associated with prefrontal activity in humans (β = 0.25, p = 0.02).

   “Secondary analyses showed relationships between prefrontal activity and dual-task cost of gait speed (β = 0.25, T = 2.90, p = 0.02)”

1. Step time variability is associated with prefrontal activity in humans (β = 0.38, p < 0.01).

   “For PD there was a significant positive relationship between step time variability and prefrontal activity (β = 0.38, T = 6.26, p < 0.01)”
