Mapping the mesoscopic connectome and cell composition of the primate brain is critical for understanding the mechanism of human brain cognition and brain diseases.

　　The Mesoscopic Brain Connectome Project (MBCP) was jointly initiated by academicians of the Chinese Academy of Sciences Muming Poo and Qingming Luo. It will bring together scientists from around the world to develop tools and technologies needed for brain mapping, map the whole-brain mesoscopic neural connection map of non-human primates and humans, and promote the diagnosis and treatment of brain diseases, brain-like intelligence and other technologies.
