Randomized trial investigates how upper limb movement influences eye tracking and cortical activity in young adults, suggesting insights for rehabilitation.
Key Points
This research aims to understand how concurrent upper limb movement and occlusion affect cortical activity during ocular pursuit.
Investigated cortical activity and network organisation in young adults during ocular tracking with and without upper limb movement.
Measured eye velocity and saccadic displacement during both oculo-manual and ocular tracking under different conditions.
Analyzed changes in cortical activation in prefrontal, parietal, and visual areas following practice in oculo-manual tracking.
Eye velocity decreased and saccadic displacement increased when the moving object was occluded.
Activity in prefrontal and frontal cortex was decreased during oculo-manual tracking compared to ocular tracking with occlusion.
Following practice, prefrontal, parietal, and visual cortex activity increased during ocular tracking without occlusion.
