第一节 脑电地形图检查的内外环境 脑电地形图检查是一种将头部微弱的生物电(脑电)活动信号通过头皮电极收集送往计算机处理的过程。虽然脑电地形图仪已具备高灵敏度和高抗干扰性能,但室内外环境的好坏仍对检查结果有很大影响。 脑电地形图室不但需要一般脑电图室基本环境,还必须具备各种诱发电位的检查要求。 The first section of the EEG topography examination of the internal and external environment EEG topographic examination is a weak head bioelectric (EEG) activity signal through the scalp electrodes collected sent to the computer processing. Although EEG topograph has high sensitivity and high anti-interference performance, the quality of indoor and outdoor environment still has a great impact on the inspection results. EEG mapping room not only needs the general environment of the general EEG room, you must also have a variety of evoked potentials of the inspection requirements.
