subesophageal zone neuron FMRFamide SE2 neuron SE2 neuron FMRF SE2 neuron Bilaterally paired (Kolhekar et al., 1997) FMRFamide expressing interneuron of the subesophageal neuromere (Schneider et al., 1993). They are located more anteriorly than the FMRFamide SE3 cells (Schneider et al., 1993). FBbt:00001981 VFB:FBbt_00001981 fly_anatomy.ontology Disambiguation: P.Taghert has confirmed that the FMRFamide-expressing SE2 cells are a distinct, non-overlapping cell population to the serotonergic SE2 cells (FBbt:00100391). Shown to be present at larval and adult stages in Schneider et al. (2993). interneuron
