Congratulations to Arpy and the Saunders Lab. Arpy has published a paper titled "Ascertaining cells’ synaptic connections and RNA expression simultaneously with barcoded rabies virus libraries" in Nature Communications. Synaptic connections are critical for brain function but are hard to measure systematically. Saunders et al report “SBARRO”, a method that uses rabies virus barcoding and single-cell RNA-seq to parallelize monosynaptic network reconstruction from molecularly-profiled single cells.
