Aperiodic Dynamics of Cell Assemblies Recruited for L1 and L2 Processing of French Wh-Dependencies Highlight a Temporo-Parietal Engagement in Syntax (2026, unknown): “Crucially, aperiodic activity also shifts in task processing [67] and has been tied to arousal [68], consciousness [69,70], and performance [71–73], reflecting close ties between aperiodic activity and functional connectivity [74].”
Aperiodic EEG and 7T MRSI evidence for maturation of E/I balance supporting the development of working memory through adolescence (2024, background): “…et al., 2020a; Podvalny et al., 2015; Ouyang et al., 2020), including a reduction in the aperiodic exponent during visuomotor and object recognition tasks relative to baseline (Podvalny et al., 2015), indicating greater predominance of excitatory activity during task as compared to baseline.”
The development of oscillatory and aperiodic resting state activity is linked to a sensitive period in humans (2023, background): “, 2021), and the negative correlation between corrected alpha power and the hf-Slope slope (Podvalny et al., 2015; Muthukumaraswamy and Liley, 2018; Hill et al., 2022).”
Glutamatergic and GABAergic Receptor Modulation Present Unique Electrophysiological Fingerprints in a Concentration-Dependent and Region-Specific Manner (2023, background): “…is dependent on chronological age (Voytek et al., 2015; Waschke et al., 2017; Dave et al., 2018; Bódizs et al., 2021; Cellier et al., 2021), task (Podvalny et al., 2015; Ouyang et al., 2020; Waschke et al., 2021), and attention (He, 2014; Donoghue et al., 2020; Thuwal et al., 2021; Waschke et…”

Separating Neural Oscillations from Aperiodic 1/f Activity: Challenges and Recommendations (2021, unknown): “For example, the 1/f exponent was shown to change with task (Ouyang et al., 2020; Podvalny et al., 2015; Waschke et al., 2021), age (Bódizs et al.”
Spectral parameterization for studying neurodevelopment: How and why (2021, unknown): “Practically, emerging evidence suggests that the aperiodic exponent systematically relates to perceptual and cognitive behaviors, such as working memory performance (Donoghue et al., 2020a; Podvalny et al., 2015; Waschke et al., 2020).”
Aperiodic and oscillatory systems underpinning human domain-general cognition (2024, unknown): “The aperiodic 1/f-like spectral pattern has been observed ubiquitously in nature and across many different modalities of neural activity 11,23,56 .”
