General Information
Term adult prothoracic 9Aalpha neuron ID (Ontology) FBbt:00052129 (Fly Anatomy)
Definition Adult GABAergic interneuron of hemilineage 9A with its soma in the prothoracic neuromere that receives input from a directionally-tuned femoral chordotonal organ (FeCO) hook neuron and is activated by fast, flexing swinging movements (Agrawal et al., 2020). It is also activated by vibration, suggesting direct or indirect input from FeCO club neurons (Agrawal et al., 2020). Different cells of this type may have different additional response properties (Agrawal et al., 2020). Its activation causes small extensions of the tibia-tarsus and femur-tibia joints (Agrawal et al., 2020).[ FlyBase:FBrf0247582 ]
