sugar-sensing neuron of the adult brain [FBbt_00058222]

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). (Miyamoto et al., 2012, Fujii et al., 2015, Miyamoto and Amrein, 2014)
