These neurons follow the anterior optic tract (AOT), then proceed dorsally on the anterior surface of the lateral horn (LH) to the dorsal side of the brain, where they turn medially to run into the superior neuropils (Schubert et al., 2018). Branches innervate the superior lateral protocerebrum (SLP), the superior intermediate protocerebrum (SIP) and the superior medial protocerebrum (SMP) (Schubert et al., 2018). Unlike other LNd neurons, they do not cross into the contralateral hemisphere (Schubert et al., 2018). There are three of these cells per hemisphere (Schubert et al., 2018).
