Bilateral neuron that innervates the lobula plates of both hemispheres with tangential arbors spanning almost the entire width of each (Wei et al., 2020). Its ipsilateral processes are postsynaptic and innervate layer 2 only (Wei et al., 2020; Shinomiya et al., 2022). Its contralateral branch follows the anterior optic tract to the contralateral lobula plate layers 1 and 2, where it has presynaptic terminals (Bausenwein et al., 1990; Wei et al., 2020; Shinomiya et al., 2022). There is one of these cells per hemisphere with its soma in the cleft between the central brain and the optic lobe (Wei et al., 2020). It is glutamatergic (Wei et al., 2020). It is activated by back-to-front motion during flight (Bausenwein et al., 1990).
