讲座内容:
The brain comprises diverse cell types that are interconnected to form specific neural circuits underlying cognition and behavior. To systematically elucidate the cellular diversity and underlying regulatory mechanisms during primate evolution, we performed large-scale spatial transcriptome, single-nucleus RNA-seq and chromatin accessibility analysis of the primate brain. By developing deep learning models for integrating multi-omics data, we derived a comprehensive cell-type taxonomy and found their laminar and regional preferences as well as neighborhood complexity. Comparative analysis revealed glutamatergic and GABAergic neuron types in the cortex of primates with layer- and subregion-specific distribution and high expression of functionally important genes. Furthermore, our analysis revealed primate-specific CREs for genes related to neurodevelopment and psychiatric diseases. Taken together, these results provide spatial underpinning for molecular understanding of organizing principles of the primate brain.
