Researchers have created a comprehensive molecular atlas of the human hippocampus, a brain region crucial for memory and cognition, using spatially resolved transcriptomics and single-nucleus RNA-sequencing. This atlas maps different cell subtypes and their organization within the hippocampus, offering a detailed understanding of their specialized functions. The study, published in Nature Neuroscience, analyzed tissue from ten human donors, revealing the spatial organization of excitatory and inhibitory postsynaptic specializations. The resulting molecular atlas and its associated data are accessible online, providing a valuable resource for future neuroscience and medicine research.
