Role of L-DOPA in spinal nociceptive reflex activity: higher sensitivity of Aδ versus C fibre-evoked nociceptive reflexes to L-DOPA.

摘要

The role of L-DOPA in spinal nociceptive reflex activity has been re-evaluated. In high spinal cats, with supraspinal loops being excluded, the onset of reflex facilitation induced by noxious radiant heat is delayed after injection of L-DOPA by 4 to 10 s,
