A temporary motor injury did not alter brain activity in the action observation network (AON) for elite gymnasts. However, the cerebellum showed increased activity when gymnasts perceived movements they could not perform due to injury.

Area of Science:

  • Neuroscience
  • Motor Control
  • Perception

Background:

  • Motor expertise enhances action perception via the action observation network (AON).
  • The impact of temporary motor injury on AON activation remains unexplored.

Purpose of the Study:

  • To investigate how temporary motor impairment affects brain activity within the AON.
  • To explore the role of the cerebellum in perceiving feasible versus unfeasible movements during injury.

Main Methods:

  • fMRI was used to record brain activity in 13 elite female gymnasts.
  • Activity was measured twice: during a lower extremity injury and after full recovery.
  • Participants observed gymnastics routines they could and could not perform.

Main Results:

  • Activity in the inferior parietal lobule and MT/V5/EBA (part of AON) remained consistent regardless of injury status.
  • The cerebellum exhibited higher activation when gymnasts observed movements they were temporarily unable to perform due to injury.

Conclusions:

  • Provisional physical incapacity does not disrupt perceptual processing of body shape and motion within the AON.
  • Motor expertise may preserve sensorimotor representations.
  • The cerebellum may differentiate between perceived feasible and unfeasible movements.
