The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Relating ADHD to the aperiodic component of the EEG signal in both males and females across development (2026, unknown): “…metrics of absolute or relative power (e.g., theta/beta ratio), which confounded aperiodic and periodic activity (Donoghue et al., 2020a; Finley et al., 2022), and were until recently widely used, yet unreliable, markers of ADHD (Arns et al., 2013; Loo and Makeig, 2012; Gloss et al., 2016).”
Theta activity and cognitive functioning: Integrating evidence from resting-state and task-related developmental electroencephalography (EEG) research (2024, background): “However, the associations between resting theta/beta ratio and ADHD have not consistently replicated across studies (for reviews, see Arns et al., 2013; Lenartowicz and Loo, 2014; Loo and Makeig, 2012), and increased resting theta/beta ratio has been linked to other mental health conditions such as…”
Spectral parameterization for studying neurodevelopment: How and why (2021, unknown): “The conflating of periodic and aperiodic activity may also help explain why research findings for theta/beta and similar metrics in ADHD have been equivocal at best (Arns et al., 2013; Loo and Arns, 2015; Loo et al., 2013), and help answer calls for alternative ways to quantify differences in the po”
