腓神经Ⅰ类纤维排放不影响网状大细胞核(RMC)和中缝大核(NRM)神经元活动;Ⅱ类纤维排放使46%的 RMC 诱发单位和56%的 NRM 诱发单位发生反应;Ⅲ类纤维排放使89%的 RMC 诱发单位和100%的 NRM 单位发生最大反应。在重复刺激腓神经的条件下,41%的 RMC 受试单位和75%的 NRM 受试单位的诱发放电随刺激间隔时间的延长而增强;双脉冲刺激比单脉冲刺激更易引起 RMC 和 NRM 单位反应。RMC 和 NRM 在上述反应特征和数量分布的统计学分析上均无显著差异。本工作提示:RMC 和 NRM 是1)伤害性感受和广动力范围型反应;2)非驿站性;3)作为复合体进行活动。
The fibronectin class I fibers did not affect the activities of reticular large nucleus (RMC) and mesenchyma nucleus (NRM) neurons. Class Ⅱ fibers reacted 46% of RMC-induced cells to 56% of NRM-induced cells. Class Ⅲ fibers Emission maximizes the response of 89% of RMC-evoked units and 100% of NRM units. In repeated stimulation of the peroneal nerve, the induced discharges in 41% of RMC units and 75% of NRM units increased with longer stimulation intervals; double-pulsed stimulation was more likely to cause RMC and NRM responses than single-pulse stimulation . There was no significant difference in the statistical analysis of RMC and NRM between the above reaction characteristics and the number distribution. This work suggests that: RMC and NRM are 1) nociceptive and wide range of dynamic response; 2) non-postal sex; 3) as a complex activity.
