It sends output to the antennal lobe glomerulus VL2 posterior compartment in both hemispheres, fasciculating with the antennal commissure (Silbering et al., 2011; Benton et al., 2025). Its dendrite transduces signals from the antennal coeloconic sensillum ac1 (Benton et al., 2009). There are approximately 10-15 of these per antenna (Benton et al., 2025).
