网状巨细胞核(NGC)是延髓网状结构的一个重要核团,它在感觉传递中的作用已得到充分的肯定,但它是否参与对脊髓伤害性信息的下行抑制,研究结果不很一致。本实验的目的在于以脊髓背表面电位(CDP)为指标,观察NGC对脊髓伤害性信息的调制作用。 实验用水合氯醛浅麻醉和麻痹的Wistar大鼠。在左侧脊髓背表面(L_1
Reticular giant cell nucleus (NGC) is an important nucleus of the medulla oblongata. Its role in sensory transmission has been fully affirmed. Whether it participates in the down-suppression of spinal nociceptive information is not consistent. The purpose of this experiment was to observe the modulation effect of NGC on the nociceptive information of spinal cord by using the back surface potential (CDP) of spinal cord as an index. Experiments with chloral hydrate shallow anesthesia and paralyzed Wistar rats. In the left spinal cord back surface (L_1
