There is one of these cells per hemisphere and it innervates the entire ipsilateral mushroom body lobe system and distal pedunculus (Tanaka et al., 2008; Li et al., 2020). Its cell body fiber bifurcates in the superior neuropils, with one branch entering the tip of the gamma lobe and the other branching to enter at the base of the alpha lobe/lateral gamma lobe and the tip of the alpha' lobe (Waddell et al., 2000; Tanaka et al., 2008). It is synapsed to and by Kenyon cells throughout the mushroom body lobes and also has outputs to dopaminergic mushroom body input neurons (DANs) and mushroom body output neurons (MBONs) (Takemura et al., 2017; Li et al., 2020). This neuron is also electrically connected to the mushroom body anterior paired lateral cell (Wu et al., 2011). It is involved in sleep and memory consolidation (Haynes et al., 2015). It is a secondary neuron (Truman et al., 2023) that develops from the DM3 neuroblast (Ito et al., 2013). Pre-synaptic terminals were identified using the pre-synaptic marker Bruchpilot in DPM neurons genetically labelled with the c316-GAL4 driver (FBti0017056) (Pitman et al., 2011). Electrical connectivity was inferred using dye coupling (Wu et al., 2011). Neurotransmitter release was assessed by immunostaining to two different serotonergic antibodies: 5HT and Ddc (Lee et al., 2011). Detectable by its large amn-expressing cell body (Waddell et al., 2000). fly_anatomy.ontology FBbt:00005780 DPM FlyBrain_NDB:10445 dorsal paired medial cell MB-DPM pedunculus of adult mushroom body mushroom body intrinsic neuron medial lobe of adult mushroom body vertical lobe of adult mushroom body secondary neuron adult mushroom body output neuron adult serotonergic neuron adult Kenyon cell adult dopaminergic mushroom body input neuron adult DM3 lineage neuron adult interneuron adult GABAergic neuron adult mushroom body anterior paired lateral cell spur of adult mushroom body unilateral
