That's (relevant for) me: task-set-dependent brain responses to delayed visual movement feedback.

ABSTRACT: Bodily self-other distinction relies on the detection of (mis)matches between predicted and actual sensory movement consequences, but the brain can also use these mismatches to update its body representation. Here, we manipulated the behavioural relevance of unpredicted (delayed) visual movement feedback during functional magnetic resonance imaging. Participants matched a target oscillation with either their real, unseen hand (RH task) or with a glove-controlled virtual hand (VH task), under varying visual feedback delays. Delays were task-relevant in the VH task (requiring visuomotor adaptation) but irrelevant in the RH task. VH > RH task execution activated the posterior parietal cortex (PPC) and extrastriate visual cortex significantly more strongly. The cerebellum showed stronger overa
