EEG 系統(tǒng)由 IX-EEG 記錄儀和 LabScribe 采集分析軟件組成,包括EEG 分析模塊。
IX-EEG 是一款 24 通道記錄儀,用于同時測量單個人體受試者的 20 個 EEG 通道、兩個生物電位通道、一個 GSR 通道和一個事件標記。用于人體心血管、神經(jīng)肌肉、精神生理學等多方面研究。
LabScribe EEG 分析軟件預設多種EEG分析模板供使用者選擇,α、β、θ、δ等腦電波頻譜分布也能夠輕易計算并呈現(xiàn),分析結果可以導出為text、EDF、Matlab等多種數(shù)據(jù)格式,方便使用者文件保存和后續(xù)分析。
主要技術參數(shù):
EEG:1-19通道,通過使用10-20腦電 帽(Ag-AgC l電極)
信號輸入 生物電:2通道,可監(jiān)測ECG、EMG、EOG等 GSR:指間皮電 模擬輸入 事件標記通道 輸入范圍 ±180mV 噪音 100Hz采樣時<1uV,500Hz采樣時<2uV 軟件 LabScribe 4
應用舉例:
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.
