EEG 系统由 IX-EEG 记录仪和 LabScribe 采集分析软件组成,包括EEG 分析模块。
IX-EEG 是一款 24 通道记录仪,用于同时测量单个人体受试者的 20 个 EEG 通道、两个生物电位通道、一个 GSR 通道和一个事件标记。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。
主要技术参数:
EEG:1-19通道,通过使用10-20脑电 帽(Ag-AgC l电极)
信号输入 生物电:2通道,可监测ECG、EMG、EOG等 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<1uV,500Hz采样时<2uV 软件 LabScribe 4
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.
