摘要

Understanding brain evolution requires detailed comparative analyses of brain structures across species. However, high-resolution anatomical and connective data remain limited for most vertebrates beyond a few well-studied model organisms. To address this gap, we collected postmortem brain samples from a range of vertebrates, primarily small amniotes, and performed magnetic resonance imaging and histological staining. Here, we present the “Animal Brain Collection (ABC),” a freely accessible database that enables researchers to examine and compare cellular and tissue-level brain architectures across species. This resource provides a foundation for cross-species investigations of brain structure and development, offering new opportunities for research into the diversity and evolution of vertebrate brains.
