Nature Neuroscience, Published online: 17 February 2026; doi:10.1038/s41593-026-02215-1Across the globe, human environments and experiences are diverse and undergoing rapid transformation. With the growing prevalence of neurological and mental health challenges, there is now an urgent imperative to understand the impacts of this diversity and change on the brain. This will require large-scale and long-term global studies of neural activity coupled with measures of lifestyle and life experience, environmental exposures, and mental and cognitive outcomes across diverse populations that lend themselves to untangling multivariate effects. We describe our experience developing large-scale EEG neuroimaging data acquisition programs in India and Tanzania and highlight key considerations for ensuring that such programs are ethically sound, cost-effective, scalable, adaptable and capable of producing high-quality data.
