STROKE-RECOVERY REORGANISATION MECHANISMS
SUMMARY
1. Recruitment of the motor networks of the ipsilateral, unaffected parts of the hemisphere[1]. Persistent ipsilateral cortical involvement is generally assoc. with larger strokes & poorer recovery.
2. Reorganization in response to training occurs along the cortical rim of the infarction with increased recruitment of secondary cortical areas such as supplementary motor area and pre-motor cortex in the contralateral (to the affected) hemisphere[2]
.
3. Reorganisation of cortex post stroke is dependent on the lesion site but also on remote brain areas with structural connections with the damaged area of the brain.
