General Information
Term larval mushroom body output neuron h1 ID (Ontology) FBbt:00047980 (Fly Anatomy)
Definition Larval neuron that has presynapses in the ipsilateral and contralateral centroposterior medial compartment (posterior inferior protocerebrum) and postsynapses in the lateral region (M2/shaft) of the mushroom body medial lobe (Saumweber et al., 2018). It is GABAergic (Eichler et al., 2017). It outputs onto FAN-8 (Eschbach et al., 2020). It develops from a DALv neuroblast (Saumweber et al., 2018) and becomes an adult MBON09 neuron during metamorphosis (Truman et al., 2023).[ FlyBase:FBrf0236359 FlyBase:FBrf0238440 FlyBase:FBrf0245294 FlyBase:FBrf0255928 ]
Also Known As "larval MBON-h1" ; "MBE13a"
Comment MBE13a synonym from catmaid. Neuroblast either DALv2 or DALv3 (Saumweber et al., 2018).
