2007 Proceedings of the National Academy of Sciences of the United States of America  
The blood oxygenation level-dependent signal fluctuations associated with each network were correlated with the EEG power variations of delta, theta, alpha, beta, and gamma rhythms.  ...  These RSNs fluctuate at frequencies between 0.01 and 0.1 Hz, and strongly overlap with sensory-motor, visual, auditory, attention, language, and default networks that are commonly modulated during active  ...  The first component involves a characteristic lateral parietal, medial parietal, and frontal pattern, with a peak in the frequency domain at 0.013 Hz, consistent with the so-called defaultmode network  ...

2011 Frontiers in Human Neuroscience  
ECoG amplitudes in the alpha, beta, and gamma bands identified neural changes associated with covert attention and motor preparation/execution in the different stages of the task.  ...  In summary, our results illustrate rich and distributed cortical dynamics that are associated with orienting attention and the subsequent motor preparation and execution.  ...  The former region is involved in spatial orientation, imagery (Strotzer, 2009 ) and attention (Lloyd, 2007) , whereas the latter has been associated with stimulus-driven (i.e., alerting) attention (  ...

2013 Cerebral Cortex  
Spontaneous activity in the human brain occurs in complex spatiotemporal patterns that may reflect functionally specialized neural networks.  ...  These spectral signatures not only allowed us to parcel the brain into clusters that resembled the brain's established functional subdivision, but also offered important clues for disentangling the involvement  ...  Notes The authors appreciate Drs Alan Koretsky and Bing Yao for helpful discussions, and Drs David Leopold and Biyu He for constructive comments on this paper. Conflict of Interest: None declared.  ...

2017 Journal of Neuroscience  
Here we tested the interaction between 10 Hz flicker and endogenous alpha-band (~10 Hz) oscillations during a selective visuospatial attention task.  ...  We show that alpha-band (10 Hz) flicker impairs stimulus processing in a selective attention task when the stimulus flicker rate matches .  ...  Thus, we hypothesized that alpha flicker could interfere with functioning of networks operating in alpha and, as a consequence, interfere with selective attention.  ...
