General Information
Term dopaminergic PAM neuron 12 ID (Ontology) FBbt:00100230 (Fly Anatomy)
Definition Dopaminergic PAM neuron whose cell body fiber runs dorsally along the anterior surface of the gamma lobe, with one branch innervating the middle part of the gamma lobe (slice 3) (Tanaka et al., 2008; Aso et al., 2014). Another branch bifurcates on the dorsal surface of the medial lobe (Tanaka et al., 2008), with one fiber having dendritic terminals in the crepine and superior medial protocerebrum behind the medial lobe (Tanaka et al., 2008; Aso et al., 2014). The fiber other turns medially through the border between the gamma and beta' lobes and enters the opposite hemisphere, where it runs horizontally, enter the medial lobe at the border between the gamma and beta' lobes and forms arborization in the middle part of the gamma lobe (slice 3) (Tanaka et al., 2008). There are approximately 11 neurons of this type per hemisphere (Tanaka et al., 2008; Aso et al., 2014; Li et al., 2020).[ FlyBase:FBrf0205263 FlyBase:FBrf0227179 FlyBase:FBrf0248215 ]
Also Known As"MB-M2 neuron" ; "mushroom body medial lobe arborizing neuron 2" ; "PAM-12" (for all, see Synonyms field below)
CommentTwo morphological clusters of individuals found in Li et al. (2020), but not clear if these are conserved between organisms.
