Fixation-Related EEG Frequency Band Power Analysis: A Promising Neuro-Cognitive Methodology to Evaluate the Matching-Quality of Web Search Results?We used fixation-related EEG frequency band power analyses to study the evaluation of web search results. Participants were presented thirteen search queries,...
此外, Gotman等将峰值频率(Peak frequency)和主频峰值带(Band width)用于对新生儿的癫痫发作检测. 利用Zibrandtsen等提出的频谱边缘频率(Spectral edge frequency, SEF)特征, 可以求出不同频率范围下对应的SEF(一般取总频谱功率80%、90%、95%之外的边缘频率), 同理利用PSD求出该对应频率范围的频谱总功率(Total sp...

联合ICA已被用于提取与运动序列学习、目标识别和静息态网络相关的BOLD信号的时空模式。例如,一种基于ICA的联合方法融合了多模态EEG和fMRI数据,可以在没有ERP振幅或相位的先验信息情况下将单试次EEG和fMRI结合起来。在这种方法中,单试次EEG响应和fMRI响应可以合并到一个矩阵中,并进行联合时空分解。另一种方法是使用ICA...

The timefrequency (TF) analysis indicated that there existed a contralateral dominance of alpha post-movement event-related synchronization (ERS) pattern during the voluntary task, and that the energy of alpha band increased in the ipsilateral area during the stimulated (median nerve of wrist) task...
