Neural pathways for the detection and discrimination of conspecific song in D. melanogaster.

•We identify and test a suite of AMMC LNs and PNs for their role in courtship hearing•Surprisingly, only two—aPN1/aLN(al)—are required for hearing in either sex•Pulse song is integrated in aPN1, and its outputs favor conspecific pulse rates•aPN1/aLN(al) may thus support both detection and identification of conspecific song
