脑电图记录的是脑细胞群的自发性、节律性电活动曲线,是招收飞行学员体检中的一项必要检查。脑电图机灵敏度高,但易受外界的电子干扰或其他因素影响而形成伪差,使图形失真。招飞体检的流动性大,场地不固定,机器经常拆装,受检者疲劳、紧张等,均易引起脑电图产生各种伪差。1机器安放首先,体检房应安排在安静、高频电磁场干扰少的房间,远 Electroencephalography records the spontaneous, rhythmic electrical activity curve of a group of brain cells and is an essential check-in for medical examinations of pilots enrolled. EEG high sensitivity, but vulnerable to external electronic interference or other factors and the formation of pseudo-poor, so distorted graphics. The examination of the flow of large sports, the venue is not fixed, the machine disassembly, the subjects fatigue, tension, etc., are likely to cause EEG various artifacts. 1 machine placement First, the physical examination room should be arranged in a quiet, high frequency electromagnetic interference less room, far
