Abstract: 目的: 通过对支配眼轮匝肌的神经上的神经电信号(ENG)的分析,监控眼轮匝肌的功能状态。
方法: 通过植入狗面神经颧支周围的cuff电极,在体记录神经电信号。分析眼轮匝肌处于舒张状态与收缩状态时ENG的差异性,以找出监控眼轮匝肌功能状态的方法。
结果: 研究中我们提取到了能反映眨眼动作发生的ENG,经时、频域分析显示,眼轮匝肌处于舒张状态时,无论这种舒张状态是处于自然睁眼期间,还是处于眨眼动作的间期,其支配神经上的神经信号是一致的;而当眼轮匝肌处于收缩状态时,其神经信号幅值和频率都明显不同于舒张状态。
结论: 可以通过对ENG的分析来监测眼轮匝肌的功能状态。
Objective: To monitor the activities of orbicularis oculi muscle by analyzing the electroneurogram (ENG) of its innervating nerve.
Methods: The ENG was recorded in vivo by a cuff electrode implanted around a dog’s zygomatic branch of facial nerve. The differences between the ENG during relaxing period of the orbicularis oculi muscle and during the constricting period were analyzed to explore a way to monitor the muscle activities.
Results: The ENG signals indicating occurrences of eye blinking events were extracted in the study. Time-frequency analysis showed that there was no ENG difference when the orbicularis oculi muscle was in relaxing periods no mater whether it was in the nature eye-opening period or in the interval of eye blinking. The ENG of orbicularis oculi muscle in constricting period was different from the ENG in relaxing period at amplitude and frequency.
Conclusion: It is feasible to monitor the orbicularis oculi muscle activities by ENG analysis.
