      Statement
      Reference

      ScerGAL4Gr5a.PUn drives expression in a subset of gustatory receptor neurons in the labellum which do not overlap with those marked by NcraQFIr76b.1.5. The projections of the ScerGAL4Gr5a.PUn-positive neurons in the subesophageal ganglion show minimal overlap with projection of neurons labelled by NcraQFIr76b.1.5.
