The paper demonstrates the feasibility of collecting high-quality EEG data in field settings in India and Tanzania using trained teams and automated quality control, achieving cost-effective large-scale data collection.

The paper introduces a new EEG metric, High Variability Periods (HVPs), which reflects brain states by analyzing amplitude variability and shows differences across conditions.

The paper shows that alpha oscillations in EEG are less prevalent and vary widely in energy among adults without modern education and technology access, suggesting modernization impacts brain dynamics.

This study measures EEG complexity across populations with different socioeconomic and geographic contexts, finding it correlates with modern experience and income.

The paper shows that EEG dynamical features scale systematically with life context, linking brain activity to modernization features like travel and fuel consumption.
