Heterogeneity in the Drosophila gustatory receptor complexes that detect aversive compounds

Nature Communications, 2017
Taste sensilla are Drosophila sensory organs containing taste neurons, which have differential tuning for bitter compounds. Here, the authors systematically examine what combinations of gustatory receptor genes confer a specific taste response profile in

Ionotropic receptors mediate nitrogenous waste avoidance in Drosophila melanogaster

Communications Biology, 2021
Dhakal et al. use chemoreceptor screening on three ionotropic receptors in Drosophila, IR25a, IR76b, IR51b to evaluate their impact on avoidance behaviors against nitrogenous waste products.

Identification of a gustatory receptor tuned to sinigrin in the cabbage butterfly Pieris rapae.

PLoS Genetics, 2021
Glucosinolates are token stimuli in host selection of many crucifer specialist insects, but the underlying molecular basis for host selection in these insects remains enigmatic.

Is fat the sixth taste primary? Evidence and implications [PDF]

, 2015
Explores our tongue\u27s ability to detect fat as a distinct taste similar to our ability to sense sweet, sour, bitter, acid and savory. Abstract Taste is the chemical sense responsible for the detection of non-volatile chemicals in potential foods. For

Mechanosensory neurons control sweet sensing in Drosophila

Nature Communications, 2016
How different sensory modalities interact to control feeding is poorly understood. Here, authors show that in Drosophila, activation of labellar mechanosensory neurons causes inhibition of sweet-sensing gustatory receptor neurons, as a result ...

Chemosensory Receptors in the Larval Maxilla of Papilio hospiton

Frontiers in Ecology and Evolution, 2022
Among the butterflies of the genus Papilio (Lepidoptera: Papilionidae), Papilio hospiton (Géné) has a geographical distribution limited to the Mediterranean islands of Sardinia (Italy) and Corsica (France).

Temporal responses of bumblebee gustatory neurons to sugars [PDF]

, 2022
The sense of taste permits the recognition of valuable nutrients and the avoidance of potential toxins. Previously, we found that bumblebees have a specialized mechanism for sensing sugars whereby two gustatory receptor neurons (GRNs) within the galeal ...

Gustatory Receptor Neurons in Manduca sexta Contain a TrpA1-Dependent Signaling Pathway that Integrates Taste and Temperature [PDF]

Chemical Senses, 2013
Temperature modulates the peripheral taste response of many animals, in part by activating transient receptor potential (Trp) cation channels. We hypothesized that temperature would also modulate peripheral taste responses in larval Manduca sexta. We recorded excitatory responses of the lateral and medial styloconic sensilla to chemical stimuli at 14 ...

Dietary Salt Levels Affect Salt Preference and Learning in Larval Drosophila

, 2011
Drosophila larvae change from exhibiting attraction to aversion as the concentration of salt in a substrate is increased. However, some aversive concentrations appear to act as positive reinforcers, increasing attraction to an odour with which they have ...

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems

International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.
A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.
