The spinal cord has new insights into injuries
Researchers have shown that post-spinal cord injury (SCI) there is a high increase in activity of the Vsx2-expressing neurons in uninjured spinal cord. This is due to increased upregulation of the circuit reorganization module in the uninjured spinal cord. Basal and induced expression of this module is maximally correlated with the temporal window of opportunity…

Years after a stroke, sciatic nerve stimulation is able to improve arm and hand movement
Researchers have implanted a pair of thin metal electrodes along the upper region of the spinal cord in the neck to target populations of nerves that control arm and hand muscles. The stimulation boosted strength, range of movement and function of the arm and hand in both women. Rendulic was able to open and close…
