TrkB expression and dependence divides gustatory neurons into three subpopulations
Neural Development, 2019 Background During development, gustatory (taste) neurons likely undergo numerous changes in morphology and expression prior to differentiation into maturity, but little is known this process or the factors that regulate it.

Topological and functional characterization of an insect gustatory receptor. [PDF]
PLoS ONE, 2011 Insect gustatory receptors are predicted to have a seven-transmembrane structure and are distantly related to insect olfactory receptors, which have an inverted topology compared with G-protein coupled receptors, including mammalian olfactory receptors ...

Central Projections of Gustatory Receptor Neurons in the Medial and the Lateral Sensilla Styloconica of Helicoverpa armigera Larvae [PDF]
PLoS ONE, 2014 Food selection behavior of lepidopteran larvae is predominantly governed by the activation of taste neurons present in two sensilla styloconica located on the galea of the maxilla. In this study, we present the ultrastructure of the sensilla styloconica and the central projection pattern of their associated receptor neurons in larvae of the heliothine ...

Light and Hydrogen Peroxide Inhibit C. elegans Feeding through Gustatory Receptor Orthologs and Pharyngeal Neurons [PDF]
Neuron, 2015 While gustatory sensing of the five primary flavors (sweet, salty, sour, bitter, and savory) has been extensively studied, pathways that detect non-canonical taste stimuli remain relatively unexplored. In particular, while reactive oxygen species cause generalized damage to biological systems, no gustatory mechanism to prevent ingestion of such ...

Multimodal stimulus coding by a gustatory sensory neuron in Drosophila larvae [PDF]
Nature Communications, 2016 While gustatory systems have been extensively studied in adult Drosophila, not much is known about taste coding at the larval stage. Here, the authors investigate gustatory receptor neurons in larvae and find single neurons are capable of responding to ...

Electrophysiological Characterization of Responses from Gustatory Receptor Neurons of sensilla chaetica in the Moth Heliothis virescens [PDF]
Chemical Senses, 2007 Discrimination of edible and noxious food is crucial for survival in all organisms. We have studied the physiology of the gustatory receptor neurons (GRNs) in contact chemosensilla (insect gustatory organs) located on the antennae of the moth Heliothis virescens, emphasizing putative phagostimulants and deterrents.

Digital, three-dimensional average shaped atlas of the heliothis virescens brain with integrated gustatory and olfactory neurons [PDF]
Frontiers in Systems Neuroscience, 2009 We use the moth Heliothis virescens as model organism for studying the neural network involved in chemosensory coding and learning. The constituent neurons are characterised by intracellular recordings combined with staining, resulting in a single neuron

Identification of a Drosophila glucose receptor using Ca2+ imaging of single chemosensory neurons. [PDF]
PLoS ONE, 2013 Evaluation of food compounds by chemosensory cells is essential for animals to make appropriate feeding decisions. In the fruit fly Drosophila melanogaster, structurally diverse chemicals are detected by multimeric receptors composed of members of a ...

Cucurbitacin B Activates Bitter-Sensing Gustatory Receptor Neurons via Gustatory Receptor 33a in Drosophila melanogaster. [PDF]
Mol Cells, 2020 The Gustatory system enables animals to detect toxic bitter chemicals, which is critical for insects to survive food induced toxicity. Cucurbitacin is widely present in plants such as cucumber and gourds that acts as an anti-herbivore chemical and an insecticide. Cucurbitacin has a harmful effect on insect larvae as well.

Involvement of a Gr2a-Expressing Drosophila Pharyngeal Gustatory Receptor Neuron in Regulation of Aversion to High-Salt Foods [PDF]
Molecules and Cells, 2017 Regulation of feeding is essential for animal survival. The pharyngeal sense organs can act as a second checkpoint of food quality, due to their position between external taste organs such as the labellum which initially assess food quality, and the digestive tract. Growing evidence provides support that the pharyngeal sensory neurons regulate feeding,
