ix-eeg系统可用于记录和监测:
eeg:electroencephalography ecg:electrocardiog
emg:electromyography
eog:electro-oculogram
erp:event related potentials eda:electrodermal activityram
ix-eeg多通道脑电监测仪可从同一实验对象采集多达19通道eeg,并能同时获得2通道生物电及1通道gsr信号,广泛用于人体心血管、神经肌肉、精神生理学等多方面研究。
labscribe eeg 分析软件预设多种eeg分析模板供使用者选择,α、β、 θ、δ等脑电波频谱分布也能够轻易计算并呈现,分析结果可以导出为text、edf、matlab等多种数据格式,方便使用者文件保存和后续分析。

应用举例:
methods:data was collected using iworx (dover, nh) ixeeg hardware using a 10/20 electro-cap (eaton,oh). labscribe v3.61 software was used to run, collect, and analyze the erp data. a total of 20 participants were exposed to a sequence consisting of mrts alternating with written riddles. participants pressed a button held in their right hand when they believed they had the answer and triggered the next trial.
conclusion:peak voltage was found to happen closer to the response in the mrt task than in the written riddle task. indicating a different amount of time in the processing between the two tasks.
