The primary neurite extends anterodorsally and branches in the posterior region of the posterior ventrolateral protocerebrum, with one branch extending laterally to form postsynaptic terminals in the lobula (Matsuo et al., 2016). A ventral branch forms a dense dendritic arbor encompassing the ipsilateral antennal mechanosensory and motor center zone B, wedge, posterior lateral protocerebrum, and anterior and posterior ventrolateral protocerebrum, including the LC4 glomerulus and non-glomerular regions (Matsuo et al., 2016). A thin neurite projects medially and fasciculates with the great commissure, then turns ventrally and forms presynaptic terminals bilaterally in the saddle and posterior gnathal ganglion (Matsuo et al., 2016). Some individuals may have additional ipsilateral brain innervation (Matsuo et al., 2016). It descends on the contralateral side of the cervical connective, fasciculates with the median tract of the dorsal cervical fascicle and innervates the intermediate and lower tectulum, abdominal neuromere, and T1 and T2 leg neuropils (Namiki et al., 2018). There is one of these cells per hemisphere (Matsuo et al., 2016; Namiki et al., 2018). It receives looming stimulus input from posterior LC4 neurons and its activity results in a forwards leaning posture and forwards takeoff (Dombrovski et al., 2023). Db3a,b,c subtypes from Matsuo et al. (2016) represent individual differences in Db3 (DNp11) neurons, rather than distinct types.
