Aperiodic neural timescales in prefrontal cortex dilate with increased task abstraction (2025, unknown): “Mirror padding consists of appending a reflected version of the timeseries before and after each signal segment, before transformation to the frequency domain, and was conducted to add length to the signal and improve frequency resolution(35).”
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].”
Reevaluating the neural noise in dyslexia using biomarkers from electroencephalography and high-resolution magnetic resonance spectroscopy (2025, unknown): “…dominance of excitation over inhibition in the brain, as shown by the simulation models of local field potentials, ratio of AMPA/GABA a synapses in the rat hippocampus ( Gao et al., 2017 ), and recordings under propofol or ketamine in macaques and humans ( Gao et al., 2017 ; Waschke et al., 2021 ).”
The development of aperiodic and periodic resting-state power between early childhood and adulthood: New insights from optically pumped magnetometers (2024, unknown): “Lendner et al., 2020; Medel et al., 2023; Waschke et al., 2021).”
Model selection for spectral parameterization (2024, unknown): “They also fluctuate during cognitive tasks (Donoghue et al., 2020; Gyurkovics et al., 2022; Preston et al., 2022; Waschke et al., 2021) and reflect behavioral traits (Ostlund et al., 2021; Wilson et al., 2022).”
Aperiodic EEG and 7T MRSI evidence for maturation of E/I balance supporting the development of working memory through adolescence (2024, result): “In parallel, the amplitude of the spectra, assessed by the aperiodic offset parameter, is associated with neural spike rates (Waschke et al., 2021; Donoghue et al., 2020b), supported by intracranial LFP recordings that have shown increases in broadband LFP power associated with neuronal population…”
Aperiodic and Hurst EEG exponents across early human brain development: A systematic review (2024, unknown): “EEG 1/ f measures also display behavioural and clinical relevance, particularly in conditions thought to relate to shifts in E:I balance, including those affecting selective attention and inhibition such as attention-deficit hyperactivity disorder (ADHD) (Waschke et al., 2021; Robertson et al., 2019”
Periodic and Aperiodic EEG Features as Potential Markers of Developmental Dyslexia (2023, background): “, working memory, short-term memory, processing speed, auditory processing) [28,31,33,42,44].”
Glutamatergic and GABAergic Receptor Modulation Present Unique Electrophysiological Fingerprints in a Concentration-Dependent and Region-Specific Manner (2023, background): “…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 al., 2021).”
Oscillations and aperiodic activity: Evidence for dynamic changes in both during memory encoding (2022, background): “In particular, the power spectrum slope—or the “spectral tilt”—reflects a global aperiodic neuronal process that is modulated during visual processing [26,27] and working memory [10,28], and is implicated in memory consolidation [29].”
Time-resolved parameterization of aperiodic and periodic brain activity (2022, unknown): “Combined, the reported findings support the notion that aperiodic background neural activity changes in relation to a variety of contexts and subject types (Donoghue et al., 2020; Gao et al., 2017; Molina et al., 2020; Ostlund et al., 2021; Pathania et al., 2021; Waschke et al., 2021; van Heumen et ”
Periodic and aperiodic neural activity displays age-dependent changes across early-to-middle childhood (2021, background): “Studies have shown aperiodic activity to be modulated by task-performance (He et al., 2010), level of arousal (Lendner et al., 2020), and drug-induced states (Colombo et al., 2019; Muthukumaraswamy & Liley, 2018; Waschke et al., 2021).”
Separating Neural Oscillations from Aperiodic 1/f Activity: Challenges and Recommendations (2021, background): “For example, the 1/f exponent was shown to change with task (Waschke et al., 2021), age (He et al., 2019; Schaworonkow & Voytek, 2021; Voytek et al., 2015), and disease (Molina et al., 2020; Robertson et al., 2019) and it decreases with cortical depth (Halgren et al., 2021).”
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).”
