  • See text for information on reporter transgenes. cat-2/TH data from (Lints and Emmons 1999). Glu, glutamate; ACh, acetylcholine; VGAT, vesicular GABA transporter; VMAT, vesicular monoamine transporter; GABA, γ-aminobutyric acid. Number of “+” indicate relative levels of reporter expression.

  • a unc-47/VGAT expression in the absence of anti-GABA staining indicates usage of another neurotransmitter, perhaps glycine (see text).

  • b tdc-1 is only detected in young adult males.
