• Distributed theta networks support the control of working memory: Evidence from scalp and intracranial EEG (2025, unknown): “We investigated the spectral patterns underlying sequence maintenance and comparison using scalp EEG and intracranial EEG (iEEG) using a delayed match-to-sample (DMS) task (Cross et al., 2025; Yarbrough et al., 2025; Fig.”
• Reliable but Wrong? Automated Detection of Heart Rate Artifacts as a Source of Bias in Pediatric EEG Data (2026, unknown): “…power, with a gradual flattening of the aperiodic component with age that occurs from infancy through early adulthood, however changes to the 1/f slope may vary in both directions (flatter or steeper) depending on the child’s age and whether the individual has a neurodevelopmental condition [27, 28].”
• Relating ADHD to the aperiodic component of the EEG signal in both males and females across development (2026, unknown): “Although the relationship between the aperiodic exponent and brain structure is complex and varies with both age and region (Cross et al., 2024), our secondary “ developmental shift ” model 1 suggests that the effect of ADHD and sex (and potentially their interaction) may be better characterised by…”
• Hemispherotomy leads to persistent sleep-like slow waves in the isolated cortex of awake humans (2025, unknown): “Crucially, the spectral exponent has also been extensively studied in large pediatric samples, both during wakefulness [68–72] and NREM sleep [56,68].”
• Developmental relationships between the human alpha rhythm and intrinsic neural timescales are dependent on neural hierarchy (2025, unknown): “In addition, a large iEEG study found that the magnitude of the frequency-dependent decay in spectral power (the spectral slope) changed across development, with age-dependent changes that varied by attentional state in some regions (54).”
