The effects of stimulating periaqueductal gray (PAG) on the nociceptive neuron discharges of pronucleus evoked by stimulating the splanchnic nerve in cats were studied. The two kinds of inhibitory action were observed. One was called early phase or prompt inhibition phase which occurred within 30 ms to 150 ms after stimulation of PAG. The other was called slow-pase or sustained inhibition which occurred from a few minutes to more than ten minutes after the stimulation of PAG. The results showed that PAG played an important role in the analgesia of visceral pain. Both kinds of inhibition may be blocked by naloxone, this suggests that endogenous opiate like substances involved in these inhibitory processes caused by stimulating role in the inhibitory effect of PAG. |
