Researchers from Google and the Howard Hughes Medical Institute’s Janelia Research Campus published the largest-ever high resolution brain map of an animal. The 3D map—also referred to as a connectome—visualizes approx 25,000 of the roughly 100,000 neurons in a fruit fly’s central brain. The connectome shows where neurons connect between and within different parts of the brain that control functions like navigation, smell memory, and learning. Scientists hope the detailed map can reveal more about how those different parts of the brain work together. FlyEM, the team that created the connectome, plans to complete a larger map for a fruit fly’s entire nervous system by 2022.
