Degree centrality and fractional amplitude of low-frequency oscillations associated with Stroop interference
2015
NeuroImage
Preserved Fulltext
Here we investigated the correlation between resting-state functional magnetic imaging (fMRI) measures [degree centrality (DC)/fractional amplitude of low frequency fluctuations (fALFF)] and Stroop interference ...
Reduced Stroop interference was associated with larger DC in the left lateral prefrontal cortex, left IFJ, and left inferior parietal lobule as well as larger fALFF in the areas of the dorsal attention ...

Time-frequency-resolved EEG decoding further showed that the higher representational similarity was present in oscillations in the theta and beta frequency bands. ...
Taken together, the results suggest differences between AP and RP musicians in late pitch processing stages associated with cognition, rather than in early processing stages associated with perception. ...
The exact role of neural oscillations in perception and cognition is still somewhat of a mystery (Wang, 427 2010 ), but both theta and beta oscillations have been associated with various cognitive functions ...
