"DNA Barcodes" Enable Brain Mapping With Single-Neuron Resolution

News The new method, called MAPseq (Multiplexed Analysis of Projections by Sequencing), makes it possible in a single experiment to trace the long-range projections of large numbers of individual neurons from a specific region or regions to wherever they lead in the brain--in experiments that are many times less expensive, labor-intensive and time-consuming than current mapping technologies allow.
