Abstract

We found that electrical stimulation of the mesencephalic locomotor region (MLR) inhibited the discharge of deep dorsal horn neurons receiving group III afferent input from the triceps surae muscles. In contrast, contraction of these muscles induced by electrical stimulation of the tibial nerve activated these dorsal horn neurons. Our findings show that descending central motor commands can inhibit dorsal horn interneurons receiving input from group III afferents during exercise. Copyright (C) 2000 Elsevier Science B.V.
