Abstract
The extent and nature of tonic supraspinal influences was determined on cat spinal cord dorsal horn neurons that received both noxious (radiant heat) and nonnoxious (hair movement) inputs or only a nonnoxious input. The former cells receive a tonic inhibition that descends in the dorsolateral funiculi and which is selective for the noxious input. The latter neurons are under a tonic facilitation.
