Drives expression in the alpha and beta lobes of the mushroom body, and in a subset of ring neurons in the ellipsoid body.

ScerGAL4lilli-189Y drives expression in about 18 ring neurons R3 at 7-8 days of age.

ScerGAL4lilli-189Y in combination with ScerGAL80Mef2.mb247 drives expression in five to six neurons that densely innervate the larval antennal lobe (AL). The cell bodies of labeled neurons are located in a cluster ventrolateral to the AL.

Local interneurons in which expression is observed are also strongly GABA immunoreactive and negative for serotonin, histamine, and octopamine immunoreactivity.

Expression is observed in the ellipsoid body and alpha and beta lobes of the mushroom body, and faintly in the gamma lobe of the mushroom body.

Expression is observed in axons that occupy the inner and medial zones of the ellipsoid body, which enter the ellipsoid body through the canal and arborize throughout much of the ellipsoid body in a manner reminiscent of R3 morphology. Expression is also observed in the mushroom body pedunculus and at the ventral midline of the intersegmental nerve cord.

FlyBase curator comment: the P{GawB} insertion in the 189Y line was initially stated to be within the for gene (FBrf0096020) but has subsequently been shown to be within the lilli gene (FBrf0198702, FBrf0204617).
