摘要：

The possibility that morphine might differentially affect spinal neurons responsive to small-diameter thermoreceptive-specific afferents was tested. Systemic morphine enhanced a portion or all of the stimulus-response function of 7 of 9 lamina I spinothalamic tract cells specifically sensitive to cold applied to the glabrous hindpaw in the cat. This result contrasts strongly with the predominant inhibition of nociceptive lamina I neurons by morphine.
