Definitions of underrepresentation in neuroscience often center on a familiar set of demographic categories: gender, race and ethnicity, disability, and socioeconomic background. These classifications underpin most equity initiatives and have contributed to broadening participation. These categories, however standardized, focus on who people are—not on what systems make progress harder for them. This distinction, between identity and infrastructure, has significant consequences for who gets counted, who gets supported, and who continues to fall through the gaps.
For example, consider a researcher presenting their work in a second language, or a first-generation graduate student with no previous knowledge of how academic careers work, and no family network to absorb the financial shocks along the way. Or envision a scientist who spends months navigating visa applications just to attend a conference they’ve been invited to. These researchers are not outliers, yet they aren’t as easy to track with underrepresentation categories that exclusively rely on demographics.
Historically, our field has used definitions of underrepresentation built around demographic categories drawn from national equality legislation and census data. Some forms of underrepresentation are genuinely region-specific, such as caste identity in India or Indigenous status in New Zealand, for instance. But many diversity, equity and inclusion (DEI) initiatives designed to address these challenges overlook barriers faced by people with intersecting marginalized identities. Moreover, common proxies such as World Bank income classifications or the “Global South” can be deeply misleading—some high-income countries invest less in research as a proportion of GDP than lower-income ones, and political shocks can collapse a country’s research capacity faster than any dataset can track.
As members of the ALBA Network—a global community committed to fostering DEI in the brain sciences—we have examined these gaps closely. To address them, we argue that the field needs a more holistic approach to defining underrepresentation in global neuroscience.
We propose a broader definition that incorporates well-documented barriers to scientific participation—including the compounding disadvantages faced by LGBTQIA+ professionals; visa and mobility constraints that limit international collaboration; the invisible tax of caregiving that falls disproportionately on women; forced displacement; first-generation university status; non-native English fluency; and working countries with chronically underfunded research infrastructure.
W
hat happens when you actually apply this definition? Since 2024, we have used it in granting ALBA awards, asking applicants to identify which barriers apply to their situation and to contextualize their achievements accordingly.The change has surfaced insights into our applicant population that standard definitions might have missed entirely. Across all three award cycles, the most consistently selected barriers were being a woman, a first-generation university attendee, a non-native English speaker or from a lower socioeconomic background. Passport holders with restricted travel appeared in 24 percent of our travel award applications across all three cycles—and notably higher than among lecture nominations. Representation of researchers working in countries with chronically low investment in research and development increased from 35 percent in 2024 to 47 percent in subsequent cycles, challenging the assumption that research excellence can be found only in well-resourced environments. And displaced researchers, who are navigating forced migration due to conflict or political instability, appeared at low but non-zero levels throughout.
Perhaps the most methodologically instructive changes came from refinements introduced between cycles. In 2024, we grouped women and LGBTQIA+ applicants into a single category—one of the most frequently selected. When disaggregated from 2025 onward, LGBTQIA+ identification dropped sharply across award types, suggesting that the prior aggregation had obscured differences within the combined category.
