Mental imagery of body movements engages distinct brain networks. Visual and somatomotor strategies during imagined actions lead to different stabilometric outcomes, suggesting unique neural pathway activation.

Area of Science:

  • Neuroscience
  • Motor Control
  • Cognitive Psychology

Context:

  • Mental rotation of body parts involves visual and somatomotor systems.
  • These systems may represent different pathways to achieve a common goal.
  • Understanding these distinct strategies is crucial for cognitive and motor neuroscience.

Purpose:

  • Investigate the impact of somatomotor versus visual strategies on mental simulation of postural adjustments.
  • Differentiate the neural network activation based on dominant imagery strategies.

Summary:

  • Participants performed postural tasks under conditions of rest, counting, imagined movement, and executed movement.
  • Subjects were categorized as visual or somatomotor dominant based on their imagery strategy.
  • Mental chronometry indicated imagined movements closely matched executed movements.

  • Stabilometric analysis revealed greater postural sway in somatomotor-dominant individuals during imagined movements, suggesting distinct neural network engagement.

    • Impact:

    • Findings suggest that visual and somatomotor imagery activate different cortical and subcortical brain networks.
    • This research provides insights into the neural underpinnings of motor imagery and its strategic variations.
    • Highlights the importance of individual differences in imagery strategies for understanding brain function.
