“…Increased gamma-band oscillations for recognized stimuli suggests that NPL activity subtend top-down influences of prior knowledge on bottom-up visual processing [Goffaux et al, 2004]. An increase in NPL activity is observed for the NOGO task that requires inhibitory response [van Noordt et al, 2022]. This study reiterates that NPL activity is enhanced when there is ongoing interaction between top-down and bottom-up processes.…”

“…This article relaxed the assumption that the phase-locked activity is trial invariant(at a specific frequency). Studies like [McKewen et al, 2020], [Cohen and Donner, 2013] [van Noordt et al, 2022]raised the problem of variability in phase-locked activity corrupting NPL power estimate, but no method has been proposed to solve the issue. We consider both PL and NPL amplitude to vary with trials.…”

Brain dynamics recorded via electroencephalography (EEG) is conceptualized as a sum of two components, "phase-locked" and "non-phase-locked" to the stimulus. Both activities are understood to be stemming from different neuronal mechanisms and hence accurately characterizing them is of immense importance in neuroscientific studies. Here, we discuss the drawbacks of currently used methods to separate the phase-locked and non-phase-locked activity and propose a new method that decomposes the two components simultaneously. First, we demonstrate that single-trial separation of phase-locked and non-phase-locked power is an ill-posed problem. Second, using simulations where ground truth validation is possible, we elucidate the drawbacks of the widely used averaging method and efficacy of the proposed concurrent phaser method (CPM). Using two experimental datasets, audio oddball EEG data and auditory steady-state responses (ASSR) we show how the empirical signal-to-noise estimates warrant the usage of CPM to separate phase-locked and non-phase-locked activity.

While acute aerobic exercise has been found to have a facilitative effect on task components with varied cognitive control demands in school-age children, its effects on specific neural processes evoked by a cognitive control task remain underexplored. The objective of the current study was to examine the effects of acute aerobic exercise on task-evoked midfrontal theta event-related synchronization (ERS)—which plays a crucial role in supporting cognitive control. Thirty-three preadolescent children were recruited into this within-subjects, crossover study. Participants engaged in an aerobic exercise condition and a seated rest condition in a counterbalanced order. After both conditions, participants completed a flanker task, with concurrent EEG data collection. The results revealed no differences in midfrontal theta ERS following acute aerobic exercise as compared with following the control condition. However, midfrontal theta ERS was higher during congruent trials relative to incongruent trials following control condition but not following aerobic exercise. Collectively, acute bouts of aerobic exercise do not appear to modulate the control and behavioral monitoring processes indexed by midfrontal theta ERS during cognitive control in children.
