General Information
Term giant fiber coupled neuron 3 ID (Ontology) FBbt:00049599 (Fly Anatomy)
Definition Neuron of the adult ventral nerve cord that is coupled to the giant fiber neuron (GF) via gap junctions (Kennedy and Broadie, 2018). There are five bilateral pairs of these neurons with their cell bodies positioned dorsally in the posterolateral corner of the mesothoracic neuromere (T2) (Kennedy and Broadie, 2018). These cells send out processes that first proceed ventrally in a medial-anterior direction to the inframedial bridge, where they connect with the GF and have extensive lateral and dorsal branching (Kennedy and Broadie, 2018). The main processes then reverse course to travel posterolaterally, to the ipsilateral T3 leg neuropil (Kennedy and Broadie, 2018).[ FlyBase:FBrf0241174 ]
