General Information
Term male specific 1 neuron of subesophageal ganglion (male) ID (Ontology) FBbt:00048030 (Fly Anatomy)
Definition Octopaminergic neuron of the adult male gnathal ganglion. They have postsynaptic terminals around the esophagus and presynaptic terminals in the antennal lobe, lateral horn, anterior superior medial protocerebrum, mushroom body calyx and around the esophagus. They suppress sleeping in the presence of females and provide excitatory input into the fruitless circuit, acting upstream of P1 (pMP-e) neurons (Machado et al., 2017).[ FlyBase:FBrf0239220 ]
Also Known As "male MS1 neuron of SOG" ; "male octopaminergic MS1" ; "male octopaminergic MS1 neuron of subesophageal ganglion"
Comment These neurons do not express fruitless and are also present in females (Machado et al., 2017).
