详细介绍

IX-EEG系统可用于记录和监测:

EEGElectroencephalography ECGElectrocardiog

EMGElectromyography

EOGElectro-oculogram

ERPEvent Related Potentials EDAElectrodermal 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textEDFMatlab等多种数据格式,方便使用者文件保存和后续分析。


 

 

主要技术参数:

信号输入

EEG:最多19通道,通过使用10-20脑电帽(Ag-AgC l电极)


 

生物电:2通道,可监测ECGEMGEOG

GSR:指间皮电

模拟输入

事件标记通道

输入范围

±180mV

噪音

100Hz采样时<1uV500Hz采样时<2uV

软件

LabScribe 4

 

应用举例:

   

       

MethodsData 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.

ConclusionPeak 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.
