mushroom body pedunculus-medial lobe arborizing neuron 1 |
ID (Ontology) |
FBbt:00100243 (Fly Anatomy) |
| Definition |
A neuron whose cell body is located on the inferior neuropils, lateral to the mushroom body calyx (Tanaka et al., 2008), in the dopaminergic PPL1 cluster (Aso et al., 2014). It develops from a larval mushroom body input neuron of the CP3 (DL2) lineage (Truman et al., 2023). The cell body fiber runs anteriormedially and diverges above the ellipsoid body (Tanaka et al., 2008). Its dendrite forms four main arbors, in the superior intermediate protocerebrum, superior medial protocerebrum, dorsal crepine and ventral crepine (Otto et al., 2020). Another fiber turns ventromedially and projects to the opposite hemisphere (Tanaka et al., 2008; Li et al., 2020). A third fiber (axonal) turns ventrolaterally, runs in front of the anterior surface of the gamma lobe and then below the gamma lobe, and arborizes in the spur of the gamma lobe (slice 1) and inner core of the pedunculus (Tanaka et al., 2008; Li et al., 2020; Otto et al., 2020). The contralateral fiber innervates the same mushroom body regions (Li et al., 2020). There are 1-2 neurons of this type per hemisphere (Aso et al., 2014; Li et al., 2020; Otto et al., 2020; Truman et al., 2023). It is involved in food odor attraction (Sayin et al., 2019).[ FlyBase:FBrf0205263 FlyBase:FBrf0227179 FlyBase:FBrf0243986 FlyBase:FBrf0246510 FlyBase:FBrf0248215 FlyBase:FBrf0255928 ] |

"MB-MP1" ; "PPL1-01" ; "PPL1-gamma1pedc" (for all, see Synonyms field below) |
| Comment |
Names are assigned according to the area of the mushroom body they arborize, as detailed in Tanaka et al. (2008). The PPL1 cluster was identified by TH immunostaining and using a TH-GAL4 driver (FBtp0020119) (Liu et al., 2012). 1-2 per hemisphere in Aso et al. (2014), 1 in FAFB, 2 (each with different larval precursor cell) in Truman et al. (2023). |
