On the morning of September 20, 2025, Shanghai played host to the 2025 International Symposium on Mesoscopic Brain Atlas. At this significant symposium, two major events unfolded: the announcement of the establishment of the 'International Primates Mesoscopic Brain Atlas Consortium' and the release of the 'White Paper of the International Primates Mesoscopic Brain Atlas Consortium'. These milestones signify the scientific community's official rollout of the 'Whole - Brain Mesoscopic Neural Connectivity Atlas' major scientific project, thereby formally kick - starting systematic global collaboration in primate brain atlas research.
