(2007) did not succeed in mapping the dorsal extent of the dorsal projection of this neuron. The presence of presynaptic sites was determined by immunostaining for the presynaptic marker bruchpilot (Brp) (Damulewicz and Pyza, 2011). fly_anatomy.ontology Adult s-LNv neuron that does not express Pdf (FBgn0023178). There is one of these in each ventral cluster of LN period neurons. It is located more dorsally than the s-LNv Pdf neurons (Helfrich-Forster, 2007; Rieger et al., 2006). It extends a single neurite through the medulla that invades the lamina, forming thin arborizations in the lamina cortex near the retina that terminate at the border of the fenestrated glia (Damulewicz and Pyza, 2011). In the central brain, it extends arborizations that predominantly terminate in the neuropil region close to the pars intercerebralis. This neuron also expresses ion transport peptide (ITP) (Schubert et al., 2018). It is an evening cell (Liang et al., 2016; Liang et al., 2017; Delventhal et al., 2019).
