摘　　要：目的:测定大鼠脑三叉神经诱发电位潜伏期的正常值,建立本实验室脑三叉神经诱发电位正常值数据库。方法:采用诱发电位仪,双侧刺激记录大鼠脑三叉神经诱发电位。结果:大鼠脑三叉神经诱发电位波形主要有四个波,T1、T2、T3、T4,潜伏期分别是0.7880±0.1139、1.2467 ±0.1314、1.8265±0.3703、2.5123±0.5968;左右两侧各个相应波潜伏期的样本均数无显著差异(P>0.05)。结论:该方法大鼠脑三叉神经诱发电位正常值较为稳定,可以采用同体双侧对比实验, 为进一步研究病理状态下脑三叉神经诱发电位的变化等,提供了一定的实验依据。Objective： To determine normal latency of brain trigeminal nerve evoked potentials in rat, and establish the databank of brain trigeminal nerve evoked potentials. Method： Trigeminal nerve was directly stimulated in rats by the evoked potential instrument, and got brain trigeminal nerve evoked potentials with both - sides record. Results： It contains four main waves, T1 , T2 , T3 , T4 , in the brain trigeminal nerve evoked potentials in rat, and their latencies are 0. 7880 ± 0. 1139, 1. 2467± 0. 1314, 1. 8265±0. 3703, 2. 5123±0. 5968. There is not a significant difference （P 〉 0. 05） between the wave samples of the left and right groups. Conclusion： This method can take on the better stability with normal latencies of brain trigeminal nerve evoked potentials in rat, can adopt both - sides contrast test in a case, it will be helpful to investigate the brain trigeminal nerve evoked potentials in pathological state.
