Continuously tracing brain-wide long-distance axonal projections in mice at a one-micron voxel resolution

► New device for 3-D imaging of fluorescence mouse brain at 1 μm voxel resolution ► Novel resin-embedding method for transgenic fluorescence labeled mouse brain ► Uninterrupted tracing of brain-wide, long-distance axonal projections ► Revealed several unreported and putative projection pathways in the mouse brain
