The development of theta and alpha neural oscillations from ages 3 to 24 years (2021, unknown): “Our finding has implications for interpreting prior studies that reported developmental differences in relative and absolute power of the frequency spectrum (Barry and Clarke, 2009; Bell, 2002; Buchsbaum et al., 1992; Clarke et al., 2001; Cragg et al., 2011; Dustman et al., 1999; Gasser et al., 1988”
The development of aperiodic neural activity in the human brain (2024, unknown): “Measures of regional grey matter volume (GMV) and electrophysiological activity show substantial overlap in relation to cognition, pathology 50,51 and age 52–55 , which suggests that they may be jointly explained by shared factors, such as myelination and synaptogenesis.”
Electrophysiological activity predicts children's reading ability through orthographic awareness: Evidence from a cross-sectional and longitudinal study (2025, unknown): “These findings of low frequency bands were consistent with many previous studies (Clarke et al., 2001; Meng et al., 2021; Whitford et al., 2007).”
The development of aperiodic and periodic resting-state power between early childhood and adulthood: New insights from optically pumped magnetometers (2024, background): “We found no changes in alpha power with age aligning with some studies (e.g., Clarke et al., 2001), but not others, with reports of significant age-related increases (e.g., Tr ¨ ondle et al., 2022) and decreases (e.g., Whitford et al., 2007).”
Theta activity and cognitive functioning: Integrating evidence from resting-state and task-related developmental electroencephalography (EEG) research (2024, background): “The age-related changes in relative EEG power are linked to synaptic pruning, grey matter reduction, and the maturation of the gamma-aminobutyric acid (GABA) neurotransmitter system (Feinberg and Campbell, 2010; Hashimoto et al., 2009; Smit et al., 2012; Whitford et al., 2007).”
Age-Related Characteristics of Resting-State Electroencephalographic Signals and the Corresponding Analytic Approaches: A Review (2024, background): “Another study on the age-related relationship between EEG spectral parameters and gray-and white-matter volume reported a significant decrease in the absolute power of slow-wave (0.5–7.5 Hz) in the old (51–85 years, N = 107) group compared to those of the young (18–50 year, N = 108) [32].”
Aperiodic EEG and 7T MRSI evidence for maturation of E/I balance supporting the development of working memory through adolescence (2024, background): “Prefrontal cortex (PFC) undergoes significant maturation through adolescence, including gray matter thinning (Paus et al., 2008; Whitford et al., 2007; Giedd, 2004) and changes in task-related activation (Luna et al., 2015, 2001; Bunge et al., 2002; Ciesielski et al., 2006).”
The maturation of aperiodic EEG activity across development reveals a progressive differentiation of wakefulness from sleep (2023, unknown): “This power reduction has been related mainly to synaptic pruning (Whitford, 2007), since lower synaptic density is expected to yield lower EEG amplitude.”
Resting brain activity in early childhood predicts IQ at 18 years (2023, unknown): “This age-related change is thought to be related to cortical maturation and synaptic pruning (Corning et al., 1982; Whitford et al., 2007).”
Decomposing the role of alpha oscillations during brain maturation (2020, background): “This also sheds light on the discrepancies in literature previously observed between total alpha power and relative alpha power (Clarke et al., 2001; Cragg et al., 2011; Díaz de León et al., 1988; Gasser et al., 1988; Harmony et al., 1995; Somsen et al., 1997; Whitford et al., 2007).”
