General Information

Term

larval dopaminergic DL2a neuron

ID (Ontology)

FBbt:00110346 (Fly Anatomy)

Definition

Larval dopaminergic DL2 neuron that remains ipsilateral (Selcho et al., 2009; Blanco et al., 2011). It is a primary neuron of the BLVa1/2 paired primary lineage (Hartenstein et al., 2017). Its primary neurite projects dorsally, bifurcates and terminates widely in the dorsolateral protocerebrum, including near the lateral horn, around the pedunculus and in the anteriolateral calyx (Selcho et al., 2009). The dorsomedial protocerebrum is innervated by small arborizations, mainly lateral to the pedunculus (Selcho et al., 2009). There are also arborizations in the lateral region near the posterior part of the medial lobe of the mushroom body (Selcho et al., 2009). There are approximately 4 neurons in this cluster (Blanco et al., 2011). It persists into adulthood to become a PPL2ab neuron (Hartenstein et al., 2017).[ FlyBase:FBrf0208252 FlyBase:FBrf0216686 FlyBase:FBrf0234128 ]

Also Known As

"DL2-2 neuron" ; "DL2a neuron" ; "larval dopaminergic DL2-2 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).
