An improved index of phase-synchronization for electrophysiological data in the presence of volume-conduction, noise and sample-size bias
TLDR
Two advantages of the WPLI over the PLI are demonstrated, in terms of reduced sensitivity to additional, uncorrelated noise sources and increased statistical power to detect changes in phase-synchronization. Expand
Waking State: Rapid Variations Modulate Neural and Behavioral Responses
TLDR
By taking fluctuations in state into account, neural response (co)variability is significantly reduced, revealing the brain to be more reliable and predictable than previously thought. Expand
Arousal and Locomotion Make Distinct Contributions to Cortical Activity Patterns and Visual Encoding
TLDR
These findings suggest complementary roles of arousal and locomotion in promoting functional flexibility in cortical circuits and that arousal suppressed spontaneous firing and strongly altered the temporal patterning of population activity. Expand
The pairwise phase consistency: A bias-free measure of rhythmic neuronal synchronization
TLDR
A new circular statistic, the PPC (pairwise phase consistency), which is demonstrated to be a bias-free and consistent estimator of its corresponding population parameter and found to find a strong increase in rhythmic synchronization of spikes relative to the local field potential during the anticipation of sucrose delivery. Expand
Arousal and locomotion make distinct contributions to cortical activity patterns and visual encoding
TLDR
These findings suggest complementary roles of arousal and locomotion in promoting functional flexibility in cortical circuits are suggested and suggest that spontaneous firing in anticipation of and during movement was attributable to locomotion effects. Expand
Investigating large-scale brain dynamics using field potential recordings: analysis and interpretation
TLDR
Best practices on how field potential recordings (EEG, MEG, ECoG and LFP) can be analyzed to identify large-scale brain dynamics, and highlights issues and limitations of interpretation are presented. Expand
Gamma-Phase Shifting in Awake Monkey Visual Cortex
TLDR
It is found that stronger neuronal activation leads to spikes earlier in the gamma cycle, i.e., gamma-phase shifting is brought about by an interplay between overall excitation and gamma-rhythmic synaptic input and has interesting consequences for neuronal coding, competition, and plasticity. Expand
Selective Theta-Synchronization of Choice-Relevant Information Subserves Goal-Directed Behavior
TLDR
It is shown that a functional commonality of networks engaging in theta rhythmic states is that they emerge around decision points, reflecting rhythmic synchronization of choice-relevant information. Expand
Theta-activity in anterior cingulate cortex predicts task rules and their adjustments following errors
TLDR
It is reported that core aspects of cognitive control are encoded by rhythmic theta-band activity within neuronal circuits in the anterior cingulate cortex, suggesting that the theTA-cycle could serve as a temporal reference for coordinating local task selective computations across a larger network of frontal areas and the hippocampus to optimize and adjust the processing routes of sensory and motor circuits to achieve efficient sensory-motor control. Expand
Attentional Modulation of Cell-Class-Specific Gamma-Band Synchronization in Awake Monkey Area V4
TLDR
The cell-type-specific dynamics of the gamma cycle in macaque visual cortex are revealed and it is suggested that attention affects neurons differentially depending on cell type and activation level. Expand
