Drives expression in Or22a-expression neurons that project to antennal lobe glomerulus DM2.
Or22a expressing neurons project to both the ipsilateral and contralateral DM2 glomeruli.
Sensory neurons expressing Or22a innervate the DM2 glomerulus.
Axons of Or22a-expressing neurons project to the LM2 glomerulus.
Expression is observed in 20 sensory neurons in the dorsal proximal medial region of the antenna. These neurons project axons that converge on a single large dorsal medial glomerulus in the antennal lobe.
