In β1 and γ-frequency bands, pre-D exhibited reduced degree and betweenness centrality of hubs in superior, middle, inferior frontal areas in both hemispheres compared to controls. Dyslexics relied on left anterior temporal (β1,γ1), dorsolateral prefrontal cortex (γ1), while in right ...

为了调查研究关键频带和通道,文章引入了深度信念网络(DBN),以构建基于脑电图的积极,中性和消极的情绪识别模型。 利用多通道的脑电图数据提取的微分熵特征对DBN训练,研究训练后的DBNs的权重。 改变电极数为4,6,9,12通道时的识别率相对稳定,最佳精度为86.65%,甚至比原始的62通道更好。 实验表明,与不同情绪相关的...
In the current chapter (Chap. 5, Audiobook Experiment—Constant Quality ), the frequency band power of the alpha and theta EEG bands will be analyzed. As stimulus material, speech files with the length of audiobooks will be used. The degradation factors will be differing bit rate conditions ...

it would be discarded. This was happened very infrequently as most artifacts were less than 1 mV above the baseline rms voltage. Temporal and spectral features relevant for ExG-based drowsiness detection were implemented to target ocular artifacts and activity in standard EEG frequency bands releva...
BOLD signal is associated with neuronal synchronization across a number of EEG frequency bands. The powers of the alpha (8–12 Hz) and beta (12–30 Hz) bands correlate negatively with BOLD signal’s magnitude, while the gamma band (> 30 Hz) power correlates positively with BOLD signal’s ...
