| Research Abstract |
By recording the activity of first-order spinal interneuron from primary afferents, we found that 1) they could be used to the automatic augmentation of voluntary muscle force, 2) afferent input to them were facilitated during static phase of task, and 3) reafference signal was strong enough to drive these interneurons.
