Phase- and amplitude-coupling are tied by an intrinsic spatial organization but show divergent stimulus-related changes
… large-scale FC in electrophysiology. Phase coupling (PhC), defined as coupling between the phases of two signals, reflects the synchronization of rhythmic oscillation cycles. Conversely, amplitude coupling (AmpC), defined as coupling between the envelopes of two signals, reflects correlation …

No tDCS Augmented Working Memory Training Benefit in Undergraduates Rewarded with Course Credit
… alpha power, and strengthened theta-gamma phase amplitude coupling. Objective: To determine whether tDCS to frontal or parietal sites optimized WM training gains we pre-registered a tDCS-WM training study. Methods: 80 undergraduates were randomly assigned to one of four anodal tDCS montages: …

Advanced Bioelectronic and Microphysiological Systems for Functional Studies of Stem Cell-Derived Neural Models
… shifts in firing rate, synchrony, and phase-amplitude coupling. • Neuroweb enabled the detection of cross-species differences in signalling using air-liquid interface cerebral organoids and changes in oscillatory activity possibly linked to metabolic recycling. • The development of a full GUI …

Weaving the Past into an Imagined Future: Episodic Future Thinking Relies on Working Memory as a Cognitive Interface with Episodic Memory
… this behavioral effect corresponded with reduced coupling between the dorsomedial prefrontal cortex and right temporoparietal junction. Events imagined while simultaneously manipulating items in WM took longer to construct than events imagined during control trials and were associated with less …

Cerebellar Coordination of Neuronal and Behavioral Rhythms
… a nonparametric spectral method, and the phase amplitude coupling (PAC) of LFP oscillations within and between each structure. Resting-state coherence of gamma oscillations between LS and mPFC was significantly increased in ataxic mice relative to their controls. Ataxic animals also showed …

Exploring the neural mechanisms underlying the speech processing and phonological deficits that characterise individuals with dyslexia
… potentials (ERPs), and cross-frequency coupling, including phase-amplitude coupling (PAC) and phase-phase coupling (PPC). PAC and PPC analyses were performed across all paradigms for the delta-theta, delta-beta, delta-low gamma, theta-beta, and theta-low gamma pairs. Additionally, …

Coupled Correlates of Attention and Consciousness
… development of attentional BCIs.</p> <p>Phase amplitude coupling (PAC) of neural oscillations has been suggested as a mechanism for organizing local and global brain activity across regions. While evidence suggests that delta-high-gamma PAC, which includes very low frequencies (i.e. delta, 1-3 …
