General Information
Term larval dopaminergic DL2b neuron ID (Ontology) FBbt:00110347 (Fly Anatomy)
Definition Larval dopaminergic DL2 neuron of the larval brain with a contralateral projection (Selcho et al., 2009; Blanco et al., 2011). It is a primary neuron of a BLVa primary lineage (Hartenstein et al., 2017). The primary neurite turns in the basolateral protocerebrum towards the midline and bifurcates before reaching the esophagus (Selcho et al., 2009). It then innervates the basal protocerebrum on both sides of the brain and extends to innervate the ipsilateral posterior subesophageal ganglion (Selcho et al., 2009). A secondary neurite extends contralaterally via the dorsoposterior commissure (Selcho et al., 2009). There are also arborizations in the dorsal parts of the basolateral protocerebrum and terminals surrounding the contralateral pedunculus of the mushroom body (Selcho et al., 2009). There are 2 neurons in this cluster (Blanco et al., 2011). It persists into adulthood to become a PPL2c neuron (Hartenstein et al., 2017).[ FlyBase:FBrf0208252 FlyBase:FBrf0216686 FlyBase:FBrf0234128 ]
Also Known As "DL2-3 neuron" ; "DL2b neuron" ; "larval dopaminergic DL2-3 neuron"
Comment Dopaminergic cells were identified by double labeling with a tyrosine hydroxylase (anti-TH) antibody and a TH-GAL4 driver (FBtp0020119) (Selcho et al., 2009) and with a tyrosine hydroxylase (anti-TH) antibody (Blanco et al., 2011).
