INHIBITORY EFFECTS OF INTRACAROTID INJECTIONS OF MONOAMINES ON THE CORTICAL SPLANCHNIC EVOKED POTENTIALS |
| |
| Abstract: | The inhibitory effects of intracarotid injections of serotonin,nor-adrenaline or adrenaline indifferent doses on averaging cortical splanchnic evoked potentials,indicating the central pain response,were observed in 27 cats.Furthermore,combination of intracarotid injection of noradrenaline in sub-effective dose and electro-needling the acupoint “Weishu” with low intensity had a facilitating effecton the inhibition.The results suggest that the monoamines in peripheral circulation may enter thebrain and inhibit the cortical electroactivity,and may have a facilitating effect on acupunctureanalgesia.This work supports the results observed in our previous cross-circulation experiments,i.e.humoral factors play a role in the central action of acupuncture analgesia. |
