眼球震颤(以下简称眼震)是前庭系统异常的常见体征,在中枢性和周边性病变的鉴别中有重要价值。当眼球活动时,角膜-视网膜静息电位改变,电场分布也发生改变。眼震电图机系用置于眼球近邻的电极,将眼球活动时所产生的电位差异出,并加以放大和记录成图形的一种仪器。用这种仪器所记录下来的图形,即为眼震图。在毛主席关于“独立自主、自力更生”的伟大方针指引下,我们自行设计并制成了全部国产的全晶体管差动式直流放大微伏级的眼震电图机(图1),并 Nystagmus (hereinafter referred to as nystagmus) is a common sign of abnormalities of the vestibular system, in the central and peripheral lesions have important value in the identification. When the eye activity, the cornea - retinal resting potential changes, the electric field distribution also changed. The electromyography system uses an electrode placed in the immediate vicinity of the eyeball to differentiate the potential generated by the eyeball activity and to magnify and record it as a graphical instrument. The graph recorded with this instrument is the nystagmus. Guided by Chairman Mao’s great guideline of “independence and self-reliance”, we designed and manufactured all domestically produced all-transistor differential DC micro-voltammetric electro-oculogram machines (Figure 1)
