2023, Trends in Ecology and EvolutionChapter 3 Neurogenetics of Courtship and Mating in Drosophila
2008, Advances in GeneticsCitation Excerpt :The main gustatory processing centers in the fly are the SubesOphageal Ganglion (SOG) and the tritocerebrum. These ventral regions of the brain receive inputs from the labellum via the labial nerve; gustatory sensory neurons in the pharynx send their axons to the tritocerebrum through either the pharyngeal nerve or the accessory pharyngeal nerve (Nayak and Singh, 1985; Rajashekhar and Singh, 1994; Shanbhag and Singh, 1992; Stocker and Schorderet, 1981). Using regulatory sequences cloned from a subset of the Gustatory-receptor (Gr) genes, which drove marker expressions differentially in the relevant peripheral tissues, Wang et al. (2004) demonstrated that a given projection pattern into the CNS (see shortly below) is dependent on the specific tastant received by the GRN in question (as previewed above).

2004, Current BiologyCitation Excerpt :The primary taste-processing centers in the fly brain are the subesophageal ganglion and the tritocerebrum, which receive direct input from all GRNs in the labellum, the pharynx, and some GRNs in the legs [34–40]. Retrograde labeling experiments of neurons associated with single labellar bristles have revealed a complex arborization pattern of axon termini in the Drosophila brain [34–40]. These investigations have also established that axons of chemosensory neurons located in the labellum project through the labral nerve (LN) into the SOG.
Spatially restricted expression of candidate taste receptors in the Drosophila gustatory system
2001, Current BiologyCitation Excerpt :Flies with the drivers P [22e]→Gal4 and P [66a]→Gal4 were crossed to a UAS→lacZ or UAS→Tau-lacZ line. Tau-LacZ is a Tau-β-Gal fusion protein that is preferentially localized in axons and dendrites [37]. Flies with the driver P [66a]→Gal4 show distinct staining of the labial and accessory pharyngeal nerves (Figure 6b, left panel), and this staining reflects the expression of this gene in neurons of the labial palps and the labral/cibarial sense organs (Figure 5c).
