The construct we described as moody-GAL4 has a name that was assigned to a different construct in a previously published paper. In this paper, it should be referred to as SPG-GAL4 (for 'sub-perineural-glia-GAL4'). This construct was a gift from R. Bainton (University of California San Francisco School of Medicine). The construction and activity of this promoter will be published elsewhere (R. Bainton, personal communication). The error has been corrected in the PDF version of the article.
