Contact tracing data reveal how a One Health approach underpinned by dog vaccination interrupts rabies transmission in reservoir populations removing the risk to humans, while virus genome data highlight the importance of surveillance and sustained dog vaccination in connected populations.

Barcoded rabies virus tracing combined with single-cell RNAseq and in situ sequencing achieves high-throughput retrograde projection mapping and synaptic connectivity mapping at cellular resolution.

Whole-brain in- and outputs of inhibitory and excitatory neurons located in distinct subregions of the mouse insular cortex were mapped using viral-tracing strategies.

A brain-wide mapping of the direct inputs to striatal cholinergic and parvalbumin interneurons reveals connectivity differences and implies their distinct roles in regulating striatal function.

Under typical monosynaptic rabies tracing conditions about 40% of first-order presynaptic synapses to cortical neurons are labeled and spread efficiency does not vary depending on the distance of synapses to the cell body, across dendrite types, or starter neuron types.

Multiple trans-synaptic tracing methods reveal that there is no spatial segregation between flexor and extensor premotor interneurons in the lumbar spinal cord.

Retrograde tracing of the neural circuits that control movement of the jaw and tongue reveals how shared premotor neurons help to ensure coordinated muscle activity.

A lineage-based intersectional genetic approach reveals brain-wide distribution and input connectivity of axo-axonic interneuron cells and establishes experimental access to study the circuit function of a ground truth cell type.

Populations of spinal cord neurons innervate motoneurons controlling local and distant synergist and antagonist muscles.

A modified viral strategy reveals that ventral tegmental area dopamine cells receive substantial inputs from local sources, including distributed GABAergic and serotonergic inputs from the midbrain as well as extensive inputs from other midbrain dopamine cells.
