ScerGAL4Or67d.6.1 is expressed in the olfactory receptor neurons of a band of trichoid sensilla that extends across the central region of the antenna, and extend axons into the antennal lobe to arborize in antennal lobe glomerulus DA1. Expression of ScerGAL4Or67d.6.1 is seen in non-neuronal antennal epidermal cells. These cells lie in a range extending from the proximomedial limit of the trichoid sensilla to the distolateral tip of the antenna, but ScerGAL4Or67d.6.1 shows little to no expression in the epidermal cells lying in the proximomedial region of the antenna.
