Science chats with health economist Shailender Swaminathan about how compact EEGs could reveal the impact of culture and environment on the brain



Summary

Health economist Shailender Swaminathan believes compact, portable EEG devices offer a powerful tool to study the brain’s response to cultural and environmental factors in real-world settings. Unlike traditional lab-based EEGs, these devices allow for longitudinal data collection in diverse communities, potentially revealing how factors like pollution, social interaction, and economic conditions affect brain activity. This opens new avenues for understanding disparities in cognitive development and mental health. Swaminathan envisions using this technology to inform policy interventions aimed at optimizing environments for healthier brain development and mitigating the negative impacts of social determinants of health.
