Contribution of cognitive functions to postural control in anticipating self-paced and externally-triggered lower-limb perturbations.

DISCUSSION: We confirm that the preparatory activity of premotor areas is associated with the intentional engagement of upcoming actions since it occurs only before self-paced perturbations. The PFC anticipating both perturbations can be interpreted as an unintentional top-down cognitive control required by the tasks, especially involving attention and inhibition. However, before externally-triggered perturbations also other cognitive resources are required. The EBA activity anticipating externally-triggered perturbation may represent a visual prediction of the desired posture.
