Visuomotor training induces network reorganisation of frontal eye field and cuneus connectivity: A task-based fMRI study.

Short-term visuomotor training is known to induce functional and structural plasticity, yet its effects on task-based functional connectivity (FC), particularly within attentional and visuomotor networks, remain underexplored. This study investigated whether such training induces task-specific network-level reorganisation, focusing on the cuneus and frontal eye field (FEF) as seeds within the dorsal attention network.Fourteen healthy adults completed a 6-week voluntary eye movement training programme originally developed for visual field rehabilitation. Functional MRI data were acquired pre- and post-training and analysed using both seed-to-voxel and region-to-region (ROI-to-ROI) FC approaches. Results: revealed significantly increased connectivity between the FEF and posterior occipital cortex, and between the cuneus and cerebellar regions. Crucially, these changes were dose-dependent, showing a significant association with individual improvements in reaction time, highlighting a functional link between network reorganisation and behavioural gains.These findings provide novel evidence that short-term training enhances consolidated, task-specific FC across sensory-motor and attentional hubs. They complement earlier reports of task-based activation and microstructural plasticity in the same cohort and brain areas, establishing task-based FC as a sensitive, functional marker of learning-induced brain adaptation across the entire dorsal attentional-motor circuit.
