有关吗啡对中枢神经系统各部位的作用,近几年来的研究报告很多但吗啡在中枢内的主要作用部位及其作用机制尚未完全闸明。自从吗啡作用的特异性受体分离出来后以及内源性的类吗啡物质的发现,更增加了这方面的研究兴趣。应用电生理方法探索吗啡及内源性类吗啡物质对中枢神经系统各部位单细胞放电活动,己有许多报导。这些研究大多是在急性实验中,动物处于麻醉或麻痹状态下进行的。只能观察药物体 The role of morphine on various parts of the central nervous system, in recent years, many studies have reported that the main role of morphine in the central site and its mechanism of action has not been completely clear. Since morphine-specific receptors have been isolated and the discovery of endogenous morphine species has increased the research interest in this area. Electrophysiological methods to explore morphine and endogenous morphine substances in various parts of the central nervous system discharge activity of single cells, there have been many reports. Most of these studies were performed in acute trials where animals were anesthetized or paralyzed. Only observe the drug body
