Article Synopsis
- Motor recovery after a stroke depends on strong interactions between motor and sensory systems, requiring integration of sensory feedback for adjusting movement dynamics.
- Researchers recorded somatosensory evoked fields (SEFs) in 23 acute stroke patients at different recovery stages to study the impact of somatosensory network deficits on motor recovery.
- The findings indicated that whilst standard SEF measures from the primary somatosensory cortex did not correlate with functional recovery, the amplitude of activation in the contralateral parietal opercula was significantly associated with hand function during the acute phase and subsequent recovery.

Article Synopsis
- Stroke leads to changes in the primary somatosensory cortex, which are important for understanding recovery in motor functions after a stroke.
- Researchers studied 15 stroke patients by measuring somatosensory responses and hand function at different recovery stages post-stroke.
- Findings indicated that the affected hand's representation in the cortex temporarily enlarges during the early recovery phase, correlating with improved hand function, but later normalizes as rehabilitation progresses.
