| 摘 要： | 目的对家兔进行痛刺激间隔与诱发的事件相关电位关系的研究 ,探讨痛刺激间隔对诱发电位的影响 ,筛选兔痛觉诱发电位最优的刺激间隔。方法在家兔颅骨内F4点安放电极 ,用不同的刺激间隔按痛觉Oddball刺激序列记录该部位的波形并对其进行分析。结果痛觉P2、N2、P3a的潜伏期各刺激间隔间无显著性差异 (P >0 5 ) ,波幅在刺激间隔为 8秒时最高 (P <0 0 5 ) ,分别为 ( 63 3 3± 2 5 93 ) μv、( 62 2 5± 13 86) μv、( 5 6 17± 9 82 ) μv。 结论兔痛觉诱发电位有一最佳刺激间隔。

| Abstract: | ObjectiveTo study the effects of painful inter-stimulus interval on event-related potentials in rabbits for best inter-stimulus interval.MethodsElectrode was attached to F4 site on rabbits' skull. An Oddball paradigm stimulus were adopted. The waveforms recorded under different inter-stimulus interval were analysed.ResultsThe latency of pain evoked potentials P2,N2,P3a under different inter-stimulus interval showed no significant difference.The amplitude was highest when the interval was 8s.ConclusionsThere is a best inter-stimulus interval for pain evoked potential. |
