General Information
Term sugar-sensing neuron of the adult brain ID (Ontology) FBbt:00058222 (Fly Anatomy)
Definition Chemosensory neuron in the posterior superior lateral protocerebrum that expresses the fructose receptor Gr43a and the sugar receptor Gr64a (Miyamoto et al., 2012; Miyamoto and Amrein, 2014; Fujii et al., 2015). It senses sugars in the hemolymph to regulate feeding (Miyamoto et al., 2012; Miyamoto and Amrein, 2014; Fujii et al., 2015). There are 2-4 of these cells per brain hemisphere (Miyamoto et al., 2012; Miyamoto and Amrein, 2014; Fujii et al., 2015). They also secrete corazonin (Miyamoto and Amrein, 2014). Unlike other brain corazonin neurons, they do not project via the nervus corporis cardiaci (McKim et al., 2024).[ FlyBase:FBrf0219961 FlyBase:FBrf0224445 FlyBase:FBrf0227698 ]
