dorsal pharyngeal sense organ

ID: FBbt_00007281

Paired compound sense organ of the larval labral segment (Campos-Ortega and Hartenstein, 1997. It consists of 6 sensilla in the dorsal larval pharynx: one tri-dendritic, 2 bi-dendritic and 3 mono-dendritic (Campos-Ortega and Hartenstein, 1997. Projections generally, though not exclusively, target the contralateral subesophageal ganglion area 1 (Colomb et al., 2007. (Campos-Ortega and Hartenstein, 1997, Python and Stocker, 2002, Colomb et al., 2007)

Colomb et al., 2007 report that labral nerve projections pass through area 2 and into area 1 of the subesophageal ganglion. In the majority of cases they then target the contralateral area 2. An exception to this is one DPS fiber (which labels with Gr2a-GAL4) which targets inside area 4.
