General Information
Term leg taste bristle ascending tarsal chemosensory neuron ID (Ontology) FBbt:00047768 (Fly Anatomy)
Definition Gustatory neuron that innervates a tarsal taste bristle and ascends via the cervical connective to the brain. This includes all gustatory receptor-expressing leg taste bristle chemosensory neurons that do not express Gr5a (Kwon et al., 2014, Thoma et al., 2016, Tsubouchi et al., 2017).[ FlyBase:FBrf0225914 FlyBase:FBrf0231007 FlyBase:FBrf0237124 ]
Also Known As "atGRN" ; "leg gustatory sensillum primary neuron of brain" ; "Lgs1NB"
