The bHLH-PAS gene hlh-34 is expressed in the AVH, not AVJ interneurons

Single neuron-specific drivers are important tools for visualizing neuron anatomy, manipulating neuron activity and gene rescue experiments. We report here that genomic regions upstream of the C. elegans bHLH-PAS gene hlh-34 can be used to drive gene expression exclusively in the AVH interneuron pair and not, as previously reported, the AVJ interneuron pair.
