Identification of orbicularis oculi muscle activities based on the electroneurogram

Abstract

目的: 提取能反映眼轮匝肌功能活动的狗面神经颧支的神经电信号(ENG),通过对ENG信号的分析,识别出眼轮匝肌的功能状态。 方法: 利用植入到狗面神经颧支周围的Cuff电极提取有闭眼动作发生期间的神经电信号,采用幅度阈值法,通过对ENG信号的分析,识别出闭眼动作发生时眼轮匝肌的收缩动作。 结果: 研究中我们提取到了能反映闭眼动作发生的ENG信号,并且通过对信号的分析,识别出了眼轮匝肌收缩动作的发生。 结论: 可以通过对眼轮匝肌支配神经上ENG信号的分析,监控眼轮匝肌的功能状态。 Objective: To extract the electroneurogram(ENG) signals of a dog’s zygomatic branch of facial nerve on which the activities of orbicularis oculi muscle could be shown,and then to indentify the functional state of the muscle through analyzing the ENG. Method: The ENG during the period with some blinking events occurring was extracted by cuff electrode implanted around the dog’s zygomatic branch of facial nerve.The contraction of orbicularis oculi muscle was identified by using the Method of amplitude threshold. Result: We managed to extract the signal which could suggest the occurring of eye blinking e-vents.The contraction of orbicularis oculi muscle could be identified by analyzing the ENG. Conclusions: We could monitor the functional activities of the oculi muscle through analyzing ENG of nerve innervated the muscle.
