General Information
Term adult prothoracic 13Balpha neuron ID (Ontology) FBbt:00052128 (Fly Anatomy)
Definition Adult GABAergic interneuron of hemilineage 13B with its soma in the prothoracic neuromere that receives input from a tibial extension-sensitive femoral chordotonal organ claw neuron (Agrawal et al., 2020). It lacks action potentials, but it depolarizes or hyperpolarizes in response to tibial extension or flexion, respectively, and these responses are non-adapting (Agrawal et al., 2020). Its activation causes a slow extension of the coxa-femur joint and flexion of the femur-tibia joint (Agrawal et al., 2020).[ FlyBase:FBrf0247582 ]
