摘要
眩晕是干扰人类正常生活的一个常见症状,而前庭系统病变是产生眩晕的主要原因,因此对正常人与眩晕患者进行前庭功能相关区域的研究具有重要意义。该文主要综述前庭结构及功能的研究成果,包括正电子发射型计算机断层显像和功能性磁共振成像研究,并将经前庭冷热或直流电刺激后的健康受试者与患有急慢性外周、中枢前庭病变者的激活-负激活模式进行比对。某些特定的激活-负激活模式可以归因于不同前庭病变的功能缺损,但是对于古老前庭系统的不同感觉及感觉运动功能这个复杂难题的彻底理解还仅处于初级阶段。
Vertigo is a common symptom that interfers with the normal human life, and the vestibular system lesions are the principal causes of vertigo, so the research of vestibular function related areas of normal persons and patients with vertigo is of great significance. Here is to make a review of the research achieve- merits in vestibular structure and function, including positron emission tomography and functional magnetic resonance imaging, and comparative analysis on the activation - deactivation patterns between healthy subjects and patients with acute or chronic peripheral or central vestibular lesion during caloric or galvanic vestibular stimnlation. Although some particular e^etivatiorm artd deactivations can be attributed to functional deficits in distinct vestibular disorders, the thorough understanding of the complex puzzle of the various multisensory and sensorimotor functions of the phylogenetically ancient vestibular system is still only in its infancy.
