[The selective role of the nucleus raphe magnus in the mechanisms of analgesia in electrocutaneous pain stimulation, cold stress and the action of morphine].
Inhibition of the analgetic activity of systemic morphine and inescapable foot shock in certain moments of the experiment was shown on rats subjected to electrolytic destruction of nucleus raphe magnus. Cold swim stress increased analgesia as compared to the control animals. It is concluded that this formation of the brain is selectively and dynamically involved in mechanisms of various types of analgesia.
