K6 e9 G6 A) nAxonal projection patterns from 21 distinct cortical areas (differentially colour coded) derived from 21 mapping experiments to sample the entire cortex, and rendered in 3D by the Brain Explorer program. In this issue, Hongkui Zeng and colleagues present the first brain-wide, mesoscale connectome for a mammalian species — the laboratory mouse — based on cell-type-specific tracing of axonal projections. The wiring diagram of a complete nervous system has long been available for a small roundworm, but neuronal connectivity data for larger animals has been patchy until now. The new 3D Allen Mouse Brain Connectivity Atlas is a whole-brain connectivity matrix that will provide insights into how brain regions communicate. Much of the data generated in this project will be of relevance to investigations of neural networks in humans.
