It is unclear how the brain is affected after C7 root coaptation in brachial plexus nerve transfer procedures. In this 9.4T BOLD-fMRI rat survival study, the cortices of healthy and donor C7 rat brains are compared using images and voxel counting. Preliminary results show early decreased activation in donor rats' sensorimotor cortex.
