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。

應用舉例

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.
