Aim: It has been claimed that supraspinal structures are necessary forthe depression of nocifensive behaviour elicited by acupuncture or acupuncturelike (AL) stimulation. However, nocifensive reflexes in the spinal catwere inhibited for long periods by a mechanism releasing opieids on AL conditioning stimulation of groups II-III muscle afferents (Sj~lund and Eriksson, Neurosci.Lett. S3:264:1979).
