Cell-type-specific and Projection-Specific Brain-Wide Reconstruction of Single Neurons

Nat Methods. 2018 Dec;15(12):1033-1036. doi: 10.1038/s41592-018-0184-y. Epub 2018 Nov 19.

Abstract

We developed a dual-adeno-associated-virus expression system that enables strong and sparse labeling of individual neurons with cell-type and projection specificity. We demonstrated its utility for whole-brain reconstruction of midbrain dopamine neurons and striatum-projecting cortical neurons. We further extended the labeling method for rapid reconstruction in cleared thick brain sections and simultaneous dual-color labeling. This labeling system may facilitate the process of generating mesoscale single-neuron projectomes of mammalian brains.
