Extent of damage to descending output from cortex rather than to specific cortical regions drives the emergence of flexor synergy in non-human primates
This study demonstrates that in non-human primates, the emergence and persistence of post-stroke flexor synergies are driven primarily by the extent of damage to descending corticofugal pathways rather than by lesions to specific cortical regions, as severe and persistent synergies only occurred following large internal capsule lesions that disrupted these outputs.
