In this study, we sought a systematic way to combine EEG and fMRI signals for epileptiform localization. To this end, wedecomposed simultaneously acquired EEG and fMRI signals into their respective spatial and temporal patterns using singular decomposition (SVD), and combined them to obtain an ...
EEGandfMRIare complementary modalifieswith repect to spatiotemporal resolution.Through fusionofEEGand fMPd,hi曲spacial and temporal resolution informationabout underlyingneuro-activity canbe achieved,and thelimitationsin uni-modalanalysis ofEEGandfMRIareovercomed effectively.

功能性磁共振成像(fMRI)和脑电图(EEG)是用于测量人脑神经活动的非侵入性技术。fMRI测量的是与神经活动血流动力学变化相关的磁共振信号,具有良好的空间分辨率(2-3mm各向同性)和较低的时间分辨率(1-3s)。而EEG用于以毫秒级的时间分辨率记录大脑中的电活动,但空间分辨率有限。通过fMRI和EEG的结合,可以生成人脑功能的...
近年来,采用脑电信号(EEG)与功能磁共振成像(fMRI)多模态融合方法确定脑激活源位置、分析激活区域间连通性的方法逐步成为认知科学研究的主流。EEG/fMRI多模态融合,可以有效克服单模态分析的缺陷,形成对脑神经活动的高空间分辨率高时间分辨率分析。 论文首先分别介绍了EEG和fMRI单模态分析研究主要的问题、算法和应用,评价了...
