Exploring Neural Activities in the Prefrontal Cortex of Fragile X Syndrome Mouse Models Using Electroencephalography
… alterations in gamma power, alpha slowing, cross-frequency coupling, and reduced signal complexity, suggesting potential translational biomarkers of network dysfunction. However, the extent to which these signatures are conserved in preclinical models—especially in female mice—remains …

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 …

Exploring the neural mechanisms underlying the speech processing and phonological deficits that characterise individuals with dyslexia
… low gamma), event-related 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. …

Discerning nonlinear brain dynamics from EEG : an application to autistic spectrum disorder in young children
… and time-variable nature of the system. Time-frequency representations were first computed from the time-series to evaluate the spectral power and to categorise the ranges encompassing different activities as low-frequency (LF, 0.8-3.5 Hz), mid-range-frequency (MF, 3.5-12 Hz) or high-frequency …

Coupled Correlates of Attention and Consciousness
… 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 Hz) …
