l-LNv neuron [FBbt_00003763]
Neuron of the period-expressing LNv cluster of the adult brain, with a large cell body and generally located more dorsally than the s-LNv neurons (Helfrich-Forster, 1998). There are four of these cells present in each cluster, all of which express Pdf (FBgn0023178). These neurons send dendrites through the posterior optic commissure to the contralateral optic lobe, where a few short fibers terminate in the accessory medulla, but most arborize extensively in the medulla itself (Helfrich-Forster, 2005; Helfrich-Forster et al., 2007). These arborizations in the medulla are associated with varicosities. These cells also project to the ipsilateral (adjacent) accessory medulla and its ventral extension, where they arborize extensively. While l-LNv neurons fit the definition of pacemaker neurons based on molecular oscillation of Period (FBgn0003068) and Timeless (FBgn0014396) expression, they do not sustain this molecular oscillation when kept in constant darkness (Yang and Sehgal, 2001; Shafer et al., 2002). Synaptobrevin localization supports the assertion that projections through the posterior optic commissure to the contralateral optic lobe are dendritic (Helfrich-Forster et al., 2007).
