Minimizing toxicity of herpes simplex virus 1 (HSV) based tools for anterograde tracing is important for functional studies. Here the authors generate an anterograde monosynaptic tracer system based on HSV amplicon, which shows fast tracing, bright labeling, low toxicity, input-defined postsynaptic neurons’ anterograde monosynaptic tracing feature, and has potential for functional mapping.
