Additional Information
Statement Reference Expression is observed in a few sensory neurons of the lateral distal domain of the antenna. These neurons project both contralaterally and ipsilaterally to a small dorsal glomerulus of the antennal lobe, then extended ventrally to a larger glomerulus at the anterior of the antennal lobe. See FBrf0130146 for representative images. (Vosshall et al., 2000)
